Not the best...but I have had worse. They claim to have the "Best Tacos in America", I beg to differ...or maybe I ordered the wrong ones. I had lunch there today. The service was excellent but the food is not impressive. I ordered the Soft Chicken Taco lunch plate. The plate looked impressive with 3 chicken filled corn tortillas smothered in a ranchero type sauce. The corn tortillas used were pretty tasty as was the chicken. But the ranchero sauce, the beans and the rice were all VERY bland. I had to add a ton of salt and pepper to get some sort of flavor. I also added salsa that was served with the chips. The salsa was tasty but not spicy at all. Additionally, I believe the prices are a little to high. I paid $3.49 for a side of guacamole...it was a small spoonful of smashed avacodo served over very mild pico de gallo. I added salt and pepper to this as well.
The only thing I REALLY enjoyed was the flour tortilla served with my plate. They were delicious. Also, I tried a bite of the sopapilla and it was good too.
I wouldn't mind going back to try the nachos I saw come out of the window or even a breakfast taco (in hopes that maybe they would be the meaning behind their "Best Taco in America" claim).
