Taqueria Lucy is a venerable west-side lonchera that's been parked in the general vicinity of 27th Avenue and Buckeye Road since 2002. True, it's not the speediest food truck around — there rarely seems to be a lull at the order window, and the lines can get long at peak dinner hours. But the wide-ranging menu — everything from tacos to Sinaloan-style mariscos — rivals the flavor and quality that you'll find at many brick-and-mortar Mexican restaurants. Tacos are made on freshly made corn tortillas, and burritos are enormous, pocketbook-size affairs, stuffed with tendrils of beautifully grilled meat. The setting might seem gritty, but the food is impossibly and irresistibly delicious.
