Pleasant upscalish but casual bar on Penn Ave, close to the convention center, which serves extremely tiny tacos that are artfully prepared. I wasn't so keen on the short ribs taco (which sounded better than it is) but it was an A for concept, at least, and the fish taco was great, with nice combinations of unusual ingredients. Nice bites. They have local brews on tap and service was prompt and friendly, and the Tequila of the Day is $3. Not bad. A touch pricey, and I wouldn't go there hunting for high end haute or authentic Mexican food, but as far as fake Americanized Mexican bar food, well above average.
