I like OTB because it's consistent.
We go to OTB for Endless Enchiladas every year and they are always excellent no matter which version you choose.
Couple that with great chips and salsa (with a hint of fire roasted flavor), and you get a great place to burn a few hours with family or friends.
The atmosphere is 'modern southwestern' with interesting decorations on the walls.
The Cantina has great happy hour deals nightly and the pitcher of house margaritas with a sangria swirl is a must try...highly recommended, and only $12 during happy hour. Hurray!
