Old Town is the oldest settled area in San Diego, and is the site of the first European Settlement in present-day California. Originally there was a fort, the Presidio and a Mission. The Mission eventually moved up river. Following Mexico's independence the Spanish left town and the Presidio fell into ruins. Most of the settlers moved to what is now called Old Town. The Presidio, adjacent to Old Town, is a park with no historical structures remaining. Old Town today is a vibrant area filled with Mexican restaurants and shops with artisan goods. It's very festive. We met Kathy, Phil and Matt for Margaritas at the Rockin Lobster Baja. They were rockin Margaritas! I would recommend this joint. We went alone to dinner at Miguel's Cocina. Everywhere we have eaten at Mexican Restaurants the foodsome of the beautiful plants in Old Town.
