Thanks to everyone who recommended Casita Tacos in NoHo. Its 3 blocks from my place, and ran over based on that tip.
BEST chicken taco I've had. Really nice marinated chicken without fat or grease. Soft, apparently homemade corn tortilla...almost too fresh...it was peeling apart (but in a good way). So moist and tender!
And they have a WONDERFUL salsa negra to go with it. I am hooked...next time, I am having the quesadilla.
