We visited the Ellicott Street location. It was sunny and we wanted to sit on the patio, but there are no umbrellas to offer shade, so we opted to sit under the room, although still outside. The majority of the tables are higher with stools. We were there on a Sunday around lunch, and it was appropriate for kids. Later in the evening, probably not so much.
Here's the deal. The food is excellent. It's great taco street-food and quite authentic to Mexico, but it is quite pricey. A single taco costs at least four dollars, others are more. The drinks are sold in cans - so you get a single can of Diet Coke, for example, for $2.25. For a family of five, we ordered a single of steak fajitas (it would serve one, but we split it), four individual tacos (carne asada, al pastor, papa con rajas, and carnitas), a chicken/cheese quesadilla, queso dip, and the 3 salsa/chip platter. We left content, but hungrier people might expect more food. We also ordered four sodas. It came to $85.
Other reviewers comment on the tortillas. These are authentic, homestyle tortillas. Most people are probably used to the manufactured store bought type. Also, the salsa isn't the run of the mill red stuff you get at Chili's. Again, it's real Mexican. If you like the Chili's stuff, go there.
We will be back. Great food and ambience. Our server was fantastic. I'd recommend!
