The 3 tostada special from the U.S.S. Vallarta, along with 6 additional oysters.

I spoke a little with the people there. They started in local flea markets (Pendergrass Flea Market,  IIRC). The site in Gwinnett Place mall is their third. The advantage to the mall location is that it is open seven day a week, as opposed to just two. They talked about adding items, such as fish tacos and quesadillas, done the way you would have them served in Mexico. Perhaps it’s too food courty for some, but I’ve always been impressed by this little stall in the court in Gwinnett Place.
