Similar to Robertos, but I think the food is better is. They have the traditional taco shop staples on their menu: tacos, burritos, rolled tacos, etc.
They serve deep fried crunchy tacos, which are greasy (obviously) but delicious. The soft tacos are larger than the traditional street tacos, 2-3 of those should fill you up. I personally like the carne adobada plate- marinated beef served with choice of flour or corn tortillas. The flour tortilla is really large! It's a tasty alternative to your typical taco shop fare.
As most tacos shops, you order at the counter and self serve salsa and pick up order at the counter when called. Available salsas are red and green as one would suspect.
As others have mentioned, there is a drive through, although it could be time consuming as it usually takes 5-10 minutes for them to prepare your food. If others are ahead of you this might be time prohibitive. It's likely faster to order inside rather than drive-thru. I usually go on my lunch hour. From start to finish we can finish our meal on 30 minutes dining in (driving not included).
