I generally try places twice before I really write them off. I've now tried Caliente twice. It pains me that this place is within a minute's walk from my house yet I have zero desire to ever go back.
There is no service, the prices aren't great, and the pizza is mediocre. At least the beer is good.
My most recent experience includes waiting over five minutes before even seeing someone that works there. Once someone did show up, we were told we could sit wherever and someone would be out. Someone did show up later - it took a while though. That person was rarely seen.
About the pizza, it's pizza. It's not good pizza but it's not ... terrible. It's just mediocre. The sauce has little to no herbs or salt, the cheese is tasteless, and the toppings taste canned which is a real bummer given the outrageous price they charge you per topping.
If you want to get a beer, I guess it's okay. If someone serves you anyways. Just go to Hitchhiker or a bit further to uptown itself.
