Having lived in San Diego I have been many to a Mexican restaurant. And while I have been here once, I definitely appreciate how Añejo prepares the guacamole. Very fresh and it's made table side. Cool.
The margaritas as previously stated by fellow yelpers are outstanding. I chose to order the Ahi tuna niçoise salad and while it doesn't scream "Mexican" per say, it was perfectly prepared paired well with the hot sauces offered.
The ambience is energetic and "bustlily"( I know it's not a real word ). And be prepared to be a loud talker. Because it can get packed in there.
Overall, I'll go back there again but perhaps I'll sit outside next time though!
