Ta'Carbon is certainly not the prettiest taco spot in town. But it's nearly always the busiest. At both its west Phoenix and Glendale locations, the restaurant's mesquite grill never seems to get a rest, and the line never stops forming at the counter. The menu is simple yet complete, featuring very good carne asada, lengua, tripas, and even huevos de becerro, also known as calf fries. This is one of the few taquerias in town serving calf-fries tacos, and they are delicious. The secret to Ta'Carbon's success is not just the selection of meats, though, but the careful, studious attention paid to seasoning. Meats are consistently well-seasoned, plunked onto soft corn or flour tortillas, and left to be beautifully dressed up to your liking at the well-stocked salsa bar. Put in your order at the counter and the staff will keep track of it. It's not unusual to return to the counter two or three times over the course of a single visit.
