The San Antonio Marriott Riverwalk is turning several of its restaurants into Japanese street-food stalls for Labor Day weekend, timed to the massive crowds descending on the Henry B. González Convention Center for San Japan. Ramen bowls, curry-gravy fries, robatayaki skewers and a convenience-store-style snack counter will replace the hotel's usual dining lineup from September 4 through 6, and the activation is open to anyone walking in off the street, not just convention badge-holders.
According to CultureMap San Antonio, the hotel's seafood restaurant Current & Craft will serve three ramen bowls — a traditional tonkotsu, a creamy spicy miso, and a vegan roasted-shiitake-mushroom option — available both to eat onsite or take to go. The same three ramen bowls will also be offered at Cactus Flower, the hotel's Southwestern-themed restaurant, giving guests two spots to grab a bowl. Prices for the weekend's offerings range from $3 for a shishito pepper skewer up to $18 to $19 for the ramen bowls, per the outlet's report.
A Konbini Counter and a Front-Drive Grill
Café Carino, normally the hotel's coffee counter, will be reimagined for the weekend as a konbini-style pop-up — a nod to the ready-to-eat convenience store format that has become a global culinary trend, according to National Geographic, which notes Japan is home to more than 55,000 konbini stores nationwide. The Café Carino pop-up will stock tuna onigiri, spam musubi, egg salad sandwiches and a crispy chicken katsu sandwich served on Texas toast, blending the Japanese convenience-store format with a distinctly local touch.
Out front, Marriott chefs will staff a robatayaki pop-up at the hotel's front drive, grilling skewers of shishito peppers, pork belly, chicken thighs and tsukune chicken meatballs over open flame. The hotel will round out the menu with pork and ginger dumplings, chicken karaage served with yuzu ranch, and a mochi sundae finished with red bean fudge. It's the second straight year the Marriott has built a themed pop-up around a Japanese pop-culture moment; last year's activation was themed around K-Pop Demon Hunters, and this year's spread follows that same playbook with a street-food focus instead.
Why San Japan Draws a Captive Crowd
The timing lines up with San Japan, the anime and gaming convention that takes over the Henry B. González Convention Center for Labor Day weekend, running September 4 through 6. The convention pulled a record estimated 32,073 attendees in 2025, making it the largest event of its kind in South Texas, according to The Paisano. That's a striking jump from the roughly 900 people who showed up when the convention debuted as “San Japan: Zero Day” at Our Lady of the Lake University in 2007, a grassroots gathering started by a local student anime club.
San Japan has locked in the convention center as its permanent Labor Day weekend home through 2030, per Quit The Build, giving nearby hotels like the Marriott a reliable annual audience to plan around. The 30-story, 512-room Marriott Riverwalk sits directly across Market Street from the convention center, overlooking Hemisfair Park and the river, which makes it one of the closest dining options for attendees stepping outside the exhibit halls.
Big Business for Downtown San Antonio
The convention center itself is a major economic engine for the city. The Henry B. González Convention Center generated more than $26.5 million in revenue during fiscal year 2025 across 88 citywide events, hitting a 73% occupancy rate, according to the City of San Antonio. The 514,000-square-foot facility, which includes the largest ballroom in Texas, draws roughly 750,000 delegates annually, per the San Antonio Report.
The Marriott's food takeover also arrives amid a broader wave of culinary investment along the River Walk. Downtown hotels have been leaning into distinctive food and beverage concepts this year, including the recent debut of the 77-room Aztec Hotel, which joined Marriott's Tribute Portfolio with a rooftop restaurant and tequila lounge. With the Riverwalk corridor drawing heavier foot traffic during major events, the San Antonio Park Police's Riverwalk Patrol unit — which deploys officers on foot, bicycle and boat — works alongside the San Antonio Police Department to manage crowd safety during high-density weekends like this one.
