I'm shocked to see there aren't many great reviews for Maria Maria. My wife and I have been there several times, including a breakfast stop and always come away very happy.
The steak fajitas are so good my mouth is watering as I type this. They give you several salsas with your meal and my favorite is the chipotle style creamy sauce that comes with the fajita. This is the stuff that dreams are made of.
Also their guacamole is so good and fresh. Love the salsas as well! Everything else on the menu, though is a little off. Don't bother with the mole, it was just gross.
Very cool decor and sometimes they have live guitar. Very classy Mexican restaurant. Go for the steak fajita, guacamole and salsa.
