Re:best city for tacos on the east coast?
Surprisingly Martinsburg, WVa has a really good taco place. $1.75 will get you your choice of; Carne Asada, lingua, pork or cabezza(head meat) I'm not sure of my spelling. With salsa fresca, finely chopped onion, cilantro and fresh lime. Served on 2 corn tortillias.
I can't remember the name of the place but it is on N Queen St right across from the Weis grocery and Tractor Supply.
