Those of you who work and play downtown may have noticed that Grills on Wheels, the big black food truck that serves hearty soft shelled tacos and a killer bean and cheese burrito for a very reasonable amount of dinero, hasn't been parked at it's usual President Clinton Avenue location at the east side of the Arkansas Studies Institute. According to owner Al Aquino, for the past three weeks the staff has been on vacation, the truck is having a dented bumper repaired, and he's trying to figure out where to move, since a four story mixed-use commercial building is going up where Grills used to park. The Arcade Building, a proposed 80,000 square foot space is being developed by Moses Tucker Real Estate and, according to the firm's website, will include "retail space, office and residential space and an auditorium/theater to be developed in conjunction with the Public Library." Aquino expects Grills on Wheels to be back in business in about two weeks. He's not sure if he'll have to move at that time, but when the time comes, he plans to find another spot downtown.
