The food was very good for the Sunday buffet. But we went early to be sure the food was fresh. We figured this out from previous visits. You show up halfway through brunch and you're liable to find coagulated food or worse, next to nothing left from which to choose.
Service on the other hand, was poor to almost non-existent. When we walked in no one was there. The hostess was busy on her mobile with a phone call - I'm sure it was personal. I looked into the dining area and she asked me, "Are you looking for somebody?" I said, "No, I'm looking to eat."
She led us to a booth with heavily worn seat cushions. One had a large-ish jagged hole dead center in its vinyl covering. It looked like an open wound that wouldn't heal because someone keeps picking at the scab. Since the place was empty we slid into the next booth; the one we were given obviously needed to convalesce further.
Rather than wait for an absent server to appear, we asked the bartender where the plates were so we could get busy at the buffet tables. And it was a good thing we did, cuz we were back at our booth ready to start eating before someone showed up to take our drink order - Mimosas that weren't bad, but not great either.
The DJ was spinning a good mix of music for a Sunday morning, which made our meal a bit more enjoyable.
Yet the lack of responsible management and less than satisfactory service overshadows anything else that worked during our visit. With service suffering from a continual downward spiral affecting overall quality, TNT Tacos and Tequila isn't worth any future visits.
