Mejico, Sydney
I've been to Mejico a couple of times now and have always enjoyed it. The service has been average but sometimes you get lucky with a good server. Here are some of my recommendations:
Drinks
Guadalajaran (photo)
Mejico Signature and Classic margaritas (with the house special tequila)
White sangria
Food
Guacamole - smashed table side
Corn lollipops
Pan fried chorizo
All of their tacos
6 hour slow roasted beef brisket
Patatas Bravas
