Tia Margarita in the Outer Richmond. It's a stone's throw away from Tommy's with a bigger dining room. I'm not one for flavored margaritas, so the traditional lime is all I've had, and it's one of the best I've ever had.
I walk past Tia Margarita's regularly and, I'm sorry to say, scoff audibly more often than not. I will soon eat my scoffs, and wash them down with a margarita.
