I finally made it to Bartaco. A lunch meeting with Moin gave me the opportunity. I was slightly surprised, given tacos as a feature item, that the decor was island themed, but the room was certainly pleasant. The service is a little complex, with a couple of different types of cards that one can post, but the service itself was very gracious and helpful.
We ended up ordering two rounds. For the first round, I ordered two tacos---one chicken, one cauliflower---and a pork tamale. I liked my tacos but I loved the tamale: great filling with rich, steamy masa. On the second round, Moin ordered another taco and a vegetarian tamale. His verdict was the opposite of mine, with his clear favorite being the shrimp taco.
