The name of this lively taqueria means "Why not?", and that's the question you'll be asking yourself when thinking about ordering another taco. The choices for fillings   include carne asada and barbacoa as well as cornmeal-encrusted cod and calamari, and you should definitely consider one of the popular lime margaritas. Por Que No? also serves larger dishes like rice bowls, quesadillas, and tamale plates. It's not huge, and you'll find lines for lunch more often than not, but in good weather it's the perfect spot for sunny sidewalk dining. During happy hour (3-6pm daily and 3pm-close Tues), tacos are discounted 50 cents, and drinks are cheap, too.
