I went here on a Saturday during the day with a large group - ~20 people - for a friend's birthday. We were able to find a corner to ourselves outdoors and despite the large group we were comfortable and got good service. Everyone ordered a drink and tacos, and the waitress was quick to accommodate.
The taco was delicious - carne asada - and everyone else seemed to enjoy as well. It was about $10 for 2 which was a decent price and decent sized too. The beer I got was Tecate to get the full authentic Mexican feel, and the lime on top mixed well with it.
At about 2:00 the outside started filling up which only slightly surprised me since it was beautiful outside. I bet if I hung around longer it may have been too crowded for me, but overall it did have a nice lively feel. This is a cool place for a summer hangout sesh.
