This colorful Alphabet City taco stand sticks to the basics with fresh, generously apportioned ingredients.. The Scene A red flashing light warns potential customers of "Taco Fever," to which many passersby happily succumb. Red and multicolored strings of lights adorn the facade of this tiny orange and blue shack, with a lone employee dishing out cheap Mexican basics to a post-party crowd, who eat standing on the sidewalk with pop music playing in the background. The Food The menu might be limited, but that just means the shack focuses on making a few items well. The fish tacos, filled with tender pieces of grilled sole, are given a subtle kick from the chipotle coleslaw and radishes. Another standout dish is the nacharitos, made with a warm blend of black beans, melted cheese, salsa and cilantro layered atop a crispy tostada shell. Blue corn tortillas come stuffed with either soft chunks of chicken infused with salsa verde or smoky carne asada, overflowing with mounds of cheese, beans, salsa and cilantro.
