Went here for a going away party with some friends. Overall, meh definitely describes it. The house margaritas were only $4 during happy hour, but they pretty much tasted like a lemon slushie with a splash of tequila. The house margaritas ($7-8) were better though, and I did see people order the giant fishbowl of a drink with a Corona upside down in it.
The nacho appetizer and tacos were decent, but nothing to write home about. The guac was good so long as you don't mind chunks of raw onion in it (I do). Service was inconsistent at best. One waitress was difficult to flag down when we needed her and the other (after the shift change) was attentive and friendly.
Oh, and they added on an 18% gratuity when there were 6 of us in the group. This is one of my personal pet peeves. Besides that, after we split up the bill they tried to tack an extra $10 onto it AGAIN then claimed that was just how the computer did things. They removed it, but it left a bad taste in my mouth.
