I've been here twice, both times for Monday's trivia night hosted by the always excellent Trivia Time, and have enjoyed expedient service (s/o to the never-ending chips & salsa (both the green and red are delicious though pretty mild)) and a vibrant patio atmosphere. Both beer & ping pong tables, large Jenga and Connect 4 games, and corn hole/bags are spaced around. Though I've never been to its past life as Dos Gringos, Old Town Gringos is well kept and worth making a regular spot.
Order the tater tot nachos. I don't think I need to say anymore.
