A restaurant Carlisle really needed: simple but delicious street food at reasonable prices. Some genuine Mexican flavors here, including the excellent tacos con lengua, championes, and al pastor--plus the flor de calabaza quesadilla. Unpretentious and straightforward and filling. Plus, it's one of the few places in Carlisle that's open genuinely late: 2.30 on Fridays and Saturdays. Good for lunch, but also good for late eats.
