When you're headed east on Baltimore Street or Eastern Avenue, Mexican joints don't come out of the woodwork-they form the woodwork. It's hard to make a bad call, but Tex-Mex is THE BEST call. They've got every type of taco filling you could want, including beef tongue, goat, cactus, al pastor, chorizo, et al., all served atop two corn tortillas every bit as tasty and fresh as Tortilleria Sinaloa; it's cheaper and less crowded here, though. But, really, what you have to try is a quesadilla, folded in an extra-thick tortilla that holds up to the generous filling of whatever you choose (go with the carnitas), topped off with crisp shreds of iceberg lettuce, drizzled with near-white queso fresco, then sprinkled with grated cheese. It's a lot of salt, admittedly, but our world changed when we ate the quesadilla here. And we are better for it.
