I had high hopes for T&T as I just moved to the area. Food wasn't bad but the service was waaaaaaaaaay too slow.
Typically, a place that is 20% full on a Sunday should be able to flip a small table in under 90 minutes. I think T&T adds to the authenticity by having each order delivered from Mexico.
I would have probably tried the guacamole or cheese dip but the waitress disappeared for 15 minutes after dropping off drinks, so there wasn't too much time.
Prices weren't bad but the food was only OK, and fairly typical of similar Mexican restaurants.
