Yes, I love Carolina's. It's pretty damned good.
If you haven't been there then I suggest you check it out. Even if only to experience the atmosphere and not necessarily the food. But the food will keep you coming back.
I wish I lived closer but it's probably a good thing that I don't. I'd be eating foot-long Oaxaca burritos ($4.45) everyday. I love them. A Oaxaca burro consists of potatoes, beans, chorizo and cheese, and it's Sonoran bliss. I also love the red chile burros. I'm a burro guy so I pretty much stick to anything rolled in a tortilla.
Criticisms: Seating area sucks. Inefficient use of existing space (what's up with no seating in that first room area?), that's about it.
Definitely go there. And give me a call or a PM when you are so I can give you my order.
