Mexican cuisine is extremely regionalized; each state has its own specialties and variations on national dishes. A lot of this regionalization is due to Mexico's diverse climate. Tacos al Pastor, the late night street food where pork is sliced from a spit and layered in a corn tortilla with pineapple, originates far from the ocean in Mexico City where swine is abundant.. Ceviche, campechanas, and seafood cocteles can be found in coastal states like Baja California and Sinaloa, where fresh fish is plentiful. Tinga, a dish where shredded pork is placed in a clay pot and stewed with chipotle, tomatoes, onion, and garlic, can be traced back to the farms of landlocked Puebla. Given this incredible specialization of regions and their dishes, creating a single pan-Mexican restaurant that tackles all of the regions while maintaining quality, is no easy task.
