ARB raised $325M to grow at home. Texas receipts show what leaving looked like.

Three permits, one spring, nothing after

Mambo Seafood held three full liquor permits in San Antonio this spring. Goliad Rd at Brooks City Base, NW Loop 410 near the Medical Center, Castroville Rd on the West Side. Castroville filed its last audited beverage receipts in March 2026 and the other two in April. None has filed since, and the San Antonio press had the reason within days: CultureMap reported the Castroville closure on March 11, and MySA and the San Antonio Business Journal reported the last two closing at the end of April, Mambo's phone line telling callers it looked forward to serving them in Houston.

Four months after the last closure, on September 10, Trimontium announced $325M for Mambo's parent, Authentic Restaurant Brands, and said what it's for in one sentence: "funding the expansion of its brands within their home markets and the selective acquisition of further regional concepts." Alex Macedo, ARB's co-founder and CEO, has been saying the same thing in plainer words since at least April 2025: grow "20 minutes away, not two hours away."

ARB owns five brands and only one of them, Houston's Mambo Seafood, holds Texas permits. San Antonio, 200 miles west, was the one time under ARB ownership that the brand went two hours away.

A word on the two sources, because the piece leans on both. Texas audits on-premise alcohol sales monthly at every venue holding a full liquor permit; venues on a beer-and-wine permit file nothing. So the receipts are beverage revenue, not restaurant sales, and a beer-and-wine site is invisible in them. The state's permit roster, by contrast, lists every permit of every class with issue, surrender and expiry dates. Together they show a footprint the receipts alone couldn't.

San Antonio, unit by unit

Mambo entered San Antonio in August 2023 at 4711 NW Loop 410, a former Joe's Crab Shack whose own receipts had ended in September 2017, on a beer-and-wine permit issued that May. A second unit followed at Marbach Rd near Lackland in summer 2024, a third at Brooks City Base on Goliad Rd that fall, and a fourth on Castroville Rd in September 2025. The Marbach unit never held a full liquor permit; its beer-and-wine permit, issued January 2024, was surrendered on 6 June 2025, a month after CultureMap reported it closed.

The three that filed receipts tell the same story at different speeds. Goliad Rd opened its permit at $36.3k in October 2024, hit $53.8k in March 2025, and then settled into a range of $14k to $41k for the next year, median $25.0k. NW Loop 410 was converted from beer-and-wine to full liquor on 28 May 2025, filed $28.5k that month, drifted to $10k to $16k by winter, and stopped eleven months after the conversion. Across the whole three-unit San Antonio run, October 2024 through April 2026, the receipts total about $825,000. One Houston unit, 10810 North Fwy, filed $1.83M in the 22 months from October 2024.

The gap holds when you fix the window. Over May 2025 to March 2026, the eleven months all three San Antonio units were live, the median San Antonio Mambo venue-month was $19.9k. The median Houston Mambo venue-month was $63.4k. Both are total beverage as filed, so the comparison is like for like.

Castroville Rd is the unit that sets the timing. It opened September 8, 2025, grand opening on the 27th, 6,500 square feet and 244 seats. Its permit filed $19.0k in September, $17.1k in October, $11.1k in November, and $3.4k in March 2026. The permit was surrendered on 10 March. CultureMap ran the closure the next day, with a statement from Mambo calling it "the responsible path forward for the long-term strength of our company."

Four sources now sit side by side for each San Antonio site, and they agree to the month. Receipts stopped in March and April. Castroville's permit was surrendered in March; Goliad's and NW Loop 410's are still listed active on the September roster, which is what a permit held for transfer looks like. Google marked all three permanently closed in July. The press had the closures in March and May. A stopped filing isn't a closure on its own, but here it was, and the filing showed it first. What the tract data adds is a note on site selection: Mambo's two highest-filing Houston units sit in tracts of 29,000 and 36,000 people per square mile; the San Antonio sites matched their income profile at a fifth of the density, though Northwest Fwy files $2.47M a year at 5,400 and keeps that a hypothesis.

The control

Whether this was a Mambo problem or a San Antonio problem is a question the receipts can answer, because Mambo isn't the only Houston brand to make the trip.

BB's Tex-Orleans, Houston's Cajun-seafood chain and the closest comparator in the state, opened at 5423 W Loop 1604 N in September 2021 and is still filing in July 2026. Its San Antonio median is $33.3k a month against a Houston median of $29.1k over the same window, a ratio of 1.15. It's a smaller bar than Mambo, about half the per-unit beverage, but it travelled.

Widen the set to every Houston-origin restaurant brand whose first San Antonio permit came in 2015 or later and you get eleven brands and twenty San Antonio permits. Seventeen of those permits were still filing in the trailing twelve months, and nine of the eleven brands still have a San Antonio presence. Measured over each brand's own San Antonio window, the median brand ran at 1.18 times its Houston per-venue-month, and seven of ten with enough months ran at or above parity. Mambo's 0.31 ranks second from the bottom, above only a bar concept and level with an Irish pub that lasted a year. Nineteen venues in total, below the floor for a published rate, so this is descriptive. The direction isn't ambiguous.

What the money is actually for

The Houston columns are the other half of the story, and they're the part the release is describing.

Mambo Seafood is thirty years old and its Texas receipts begin in 2024. The permit roster explains why. Every older Houston-area site ran on a beer-and-wine permit, the earliest at 6697 Hillcroft from March 1996, and four of them were converted to full liquor between October 2024 and September 2025, each beer-and-wine permit surrendered within days of the new one being issued; McAllen and the NW Loop 410 unit in San Antonio converted the same way, and the fifth Houston filer, Cypress Creek, took over a former TGI Friday's in March 2025. All six conversions came after ARB bought the brand in 2022. Six more Houston-area sites, from Long Point to Baytown to Pasadena, still run on beer-and-wine and file nothing, which is how the brand's "13 locations" reconciles: seventeen Texas addresses on the roster, less the four San Antonio sites.

One reporting note before the numbers. Six of nine Mambo permits with revenue file all of their alcohol on the liquor line and none on the beer line, a classification habit rather than a bar without beer, since a site can't hold a beer-and-wine permit alongside a full liquor one and the old permits were surrendered at conversion. The figures below are total on-premise beverage. At Hillcroft, the online ordering menu on 13 September lists six 12-ounce bottled beers at $5.39 to $5.79, sold only with a food purchase, plus the Mambo Chelada mix by the bottle and gallon, and no liquor at all; the liquor program that drove the conversions is in-store only. The one clean counterexample is McAllen, opened October 2025 on a single permit, which splits its lines and files 80% beer.

The five Houston filers reported $10.98M over the trailing twelve months, and $3.59M from August 2025 to July 2026 excluding one month covered below, just under $68k per venue-month. The Houston seafood peer median over the comparable window, with beer counted, was $71.9k across 47 venues. May through July 2026 the five units filed $340k, $454k and $354k. And the seasonality is unmistakable: across the nine filing sites, March 2026 came in 45% above February. Lent is a seafood restaurant's December.

The release says the capital goes to home markets. The roster says it's already going there: a full liquor permit for 15838 South Fwy in Pearland was issued on 28 August 2026, thirteen days before the announcement, no receipts yet.

One thing does need explaining. In April 2026, the seven Houston and San Antonio Mambo sites held by "Mambo Seafood #N, LLC" entities filed at 11% to 27% of their March figures, then the Houston units were back to normal in May. The McAllen unit, held by a separate entity, filed 77% of March, a normal step-down from Lent. Statewide, April was ordinary by filers, taxpayers and dollars, and no Mambo taxpayer number changed. That pattern reads as an event at the numbered-LLC family rather than seven bad months, and it's the same month the San Antonio permits end. April is excluded from the per-unit figures above and put to ARB below.

The last time an ARB brand left Texas

Pollo Tropical entered Texas in 2014 under Fiesta Restaurant Group and by October 2016 had 37 permits filing receipts across DFW, Houston, San Antonio and Austin. Fiesta closed eight Texas units that month, which leaves 30, the number its annual report shows at year end. It announced the North Texas and Austin closures on April 24, 2017, and shut the last six Houston and San Antonio units on September 21.

The receipts got there first. All 38 permits had stopped filing by February 2017, two months before the April announcement and seven months before the September one. Pollo Tropical is a limited-alcohol concept, so its Texas receipts say nothing about sales. What they show is footprint and timing, and the timing is that a stopped filing led the announced closure by a season or two.

Mambo's San Antonio permits stopped in April, and the local press had the closures within days. ARB's release came in September and didn't mention them, and neither did the coverage of the raise. One thing the receipts can't tell us is what happened to the numbered LLCs' April returns. That one is ARB's to answer.

Figures in this piece are audited Texas beverage receipts at venue-month grain, receipts through July 2026, joined to the state permit roster of 8 September 2026 across all permit classes. Mambo Seafood: 17 Texas addresses, 24 permits, 10 of them full liquor. Pollo Tropical: 38 Texas permits, receipts only, since the roster drops permits expiring before 2014. Peer figures cover 13 seafood-casual brands with 47 permits within 60 miles of Houston. The Houston-to-San Antonio cohort is 11 brands and 20 permits, screened to restaurants with an uncensored Houston origin. Receipts cover on-premise alcohol only and are not restaurant revenue. Menu prices are a single online-ordering snapshot from one location and are not used for any comparison. Platform figures in the Trimontium release (225 restaurants, $1B revenue, $150M EBITDA) are the company's and can't be verified here.
