I used to go to Roberto's once or twice a week. They raised their prices (about $1.35 on average) and I havent been there since.
FOOD: 3/5. From their carne asada burritos to their rolled tacos, everything is typical for a mexican restaurant.
SERVICE: 5/5. These guys are fast. The food is made to order and it usually takes 'em about 5 min to get me my food. Even during the lunch rush.
AMBIENCE: 3/5. It's pretty much a fast food joint.
