Carlos and Pepe's has been around for years; back when there were few choices in the area. Times change, and Carlos and Pepe's just doesn't measure up.
There's a large bar with plenty of TVs that you can see from anywhere in the bar area. There's also a dining room in the back with wooden booths, but most people are in the 'Cantina'. There's soft mexican music playing and I'd have to say that the bar is attractive. The servers, unfortunately, lack personality. There's just something unfriendly about the place, as if you're bothering them when you ask for something.
As for the food, my recommendation is to stick to the drinks. They probably have the worst salsa I've ever been served. Its watery and lacks any flavor. It just seems like its weeks old. The chips; straight from a bag. The black bean soup is completely pureed and has rice in it. Enchiladas are passable, but they are a sloppy mess with a big puddle of refried beans and rice. Tomatoes and onions on the side look old. Everything here lacks any sense of freshness.
In conclusion, its a not too bad bar where you might stop for a Dos Equis before going to eat somewhere else.
