If you’re looking for a fast grab-and-go lunch with a Latin flair, go to 331 E. Bay St. and step up to the window at Taco Taco Taco. Monday-Friday at 11 a.m. the stand opens its doors to the sidewalk and begins serving hard-shelled “L.A.-style” tacos plus nachos and quesadillas. Soft drinks and cold beer are also on the menu. Part of the ClubTSI operation, it’s also open Thursday and Friday afternoons for Happy Hour and until 3 a.m. Friday and Saturday nights to feed hungry East Bay Street clubgoers. Owner Jason Grimes sets up tables, chairs and umbrellas every day on the sidewalk in front of the stand but said, “Most people get a sack of tacos to go.”
