Margarita at Canyon Café
San Diego Zoo
Deep in Cat Canyon, between the Hunt Amphitheater and the panda exhibit, the Canyon Café serves a margarita -- a real margarita, complete with ice, salt, and, yes, a modicum of tequila. It's not the best margarita you've ever tasted, but it's a reasonably good version served in a plastic cup. And just across the path is a moving stairway that takes you all the way back up...to the exit.
