I've driven past Oceanside's Mariscos Ensenada (1405 S. El Camino Real) dozens of times on my way to Target, wondering if there was anything behind their doors worth exploring (like a tiny Target, for example).
As long as Leucadia keeps nurturing little patches of quirkiness like Haggo's Organic Tacos(1114 N. Coast Hwy. 101), I think my sidewalk-eschewing, new-agey former hometown will remain firmly connected to its funky roots.
Box'd has taken over the corner of State Street and Carlsbad Village Drive (430 Carlsbad Village Drive). It's not so much a restaurant as a shipping container and a large patch of soft, artificial turf.
