The stretch of El Cajon Boulevard between 55th and 73rd streets is one of the most diverse restaurant corridors in San Diego, and most people who live outside the College Area have never eaten there. Taste of College Area fixes that in three hours. The self-guided food tour puts a wristband on your arm, a map in your hand, and sends you walking — or riding the complimentary Old Town Trolley — through 20-plus restaurants, coffee houses, and pubs serving the kind of food that only happens when a neighborhood has Vietnamese, Ethiopian, Mexican, Korean, and Mediterranean kitchens within a mile of each other. This is not a food-truck festival. These are the actual brick-and-mortar restaurants that feed the SDSU neighborhood every day, offering their best bites for one afternoon. The regulars know. If you don't live here, this is how you find out. Sunday, September 27. 11 AM to 3 PM. $40 advance, $45 day-of. Start at 6010 El Cajon Blvd.
