Ok so there's not too many Mexican restaurants in central SD, Good thing Guadalarja's is very good and reasonable too. They have a good lunch menu and if you're lucky enough to get a table they sling out the food pretty fast. There chips and salsa are free with every meal and frankly are better than dorito's, tostitio's or the like. Good service is common here. You will leave full too, they don't skimp on portions.
