I never visit Tucson without eating at "Little Poca Cosa". At least twice. Open only on weekdays and only for breakfast and lunch, the sign in the window tells you all you need to know: “Cash only. No phone. Music loud. Hugs mandatory.” Mandatory, that is, if you clean your plate. This little gem (a diminutive spinoff of the larger and muy chic Café Poca Cosa around the corner) had previously been housed for years in a what looked like Frida Kahlo’s 400-square-foot walk-in closet. A tiny spot that, after 9/11, was handed its walking papers because it was in the shadow of a federal building, suddenly too close for Homeland Security comfort. Now in its new and larger digs, it has kept its faithful well fed and has summarily enlarged its cultlike following. Take a look at my breakfast and you’ll see why folks keep coming back for more: Machaca con huevos, rice, salad, fresh fruit, beans, corn tortillas, chips & salsa...and a magnificently simple agua fresca de limón con hierbabuena. (As soon as I got home, I bought limes and searched out dried peppermint to try to make it myself.) Was I able to finish this huge meal? Hint: Marcela gave me a big hug on my way out.
