After Doug, the owner, messaged me on Yelp with some more adventurous suggestions, I grouped some co-workers together and headed back to Carrburritos. This time around, PERFECTION. I had the Tostada salad with the special chicken of the day ("Pollo a la Mexicana" - a perfectly seasoned chicken with fajitas), no cheese, no beans, but YES on sour cream. It was an AWESOME sized portion, and I cleaned my plate. Not too salty (like Chipotle can be!) and fantastic presentation. I'm definitely going for Tostadas from now on. Sometimes tostadas come in huge fried bowls, which lets be honest, are fun, but take away from the fact that you're trying to "watch it" and be health conscious. This salad had a tostada on the bottom of it that soaked up all of the salsa and was delicious, but not killer on the carbs.
Doug, thank you for the recommendations! I will absolutely be back for more. Next time, after work hours for a margarita!
