Side Street Cantina’s friendly, casual atmosphere is matched in appeal by its proximity to the oceanfront. Just a block away from sparkling waters, diners mingle over shared appetizers and platters of nachos, which they can wash down with 12- or 28-ounce margaritas. The carnitas—a favorite among regulars—pairs seasoned roast pork with a slew of rice, beans, guac, and tortillas, which make for easy transportation to mouths. Those with senses of adventure or second stomachs can take on the restaurant’s challenge of finishing the three-meat 9-pound burrito in less than 30 minutes.
