Dining Outside the Home: Los Locos Bar & Grill in San Diego, California. Tucked in the main thoroughfare of Old Town, sits an authentic unassuming Mexican cantina that serves jalapeño margaritas with a twist of outdoor music. It should. After all, this is the perfect corner spot for people-watching. For an afternoon snack, order the special of the day: Spicy Corn Nachos. Under the California sunshine, the cheese transforms into an ultra-melty obsession. Scoop up some black beans and pico de gallo. It’s okay to lick your fingers. Dishes like this are meant to be shared.
