i ditto that. i've been dragged there on multiple occasions. i've tried. aww well.
i'm afraid the op is going to have to get some nachos and hit the mezcal/tequila to get through it. thats ok, after all there is no hangover with tequila....no, really! ;)
I have been to a few birthday parties at Mezcals of various locations over the years. Stay away from anything shrimp. I would suggest the vegetable fajita's. Or load up on chips and guac. Mezcals guac is actually OK.
