While things did not work out so well for Burritoville, another Southwestern eatery had a sunnier outcome. Southwest NY served nachos, fish tacos and margaritas at 225 Liberty Street for years (the restaurant had been open since '99) until it closed last year. Well, after 12 months off, the quesadillas are back. We just got word that the concept opened at a new location that's near the original, but a little closer to the water. The Tex-Mex grub is now served in a room with big skylights and a fireplace that will heat you up if those jalapeños are not enough. The new addy is 301 South End Avenue, and the joint is open now (212-945-0528).
