La Jolla's oldest taco shop at 737 Pearl St in the Village, 92037 — a hole-in-the-wall institution since 1984 that wears its T-shirt slogan, "Ugly, gaudy, and looks like Mexico," as a badge of honor. Don Carlos runs 34 types of burrito, with the one-pound California burrito, the Hungover (breakfast meats, eggs, and fries), the Scripps (Soyrizo), and the shrimp burrito drawing the most loyalty from regulars. Rolled tacos, fried fish tacos, potato tacos, and the Don Carlos Special — rolled potato tacos with rice, beans, and a veggie burrito — fill out a menu with serious vegetarian depth, no lard or chicken stock. House-made red and green salsas come with every order. Patio faces Pearl Street. Expect a line; it moves fast.
