After over 20 years of slinging burritos, burgers, wraps, and Mexican fare, Border Grill, on Westport’s busy Post Road E, may have shut down, but in its place is another fast casual Mexican concept, Hey Taco! Behind Hey Taco! is Judd Malin, a commercial real estate professional, his wife, Edith Galvez, and Edith’s father, Hector. But make no mistake, Malin isn’t a restaurant newbie. In the past, he’s been a co-owner of four in the past, namely, F.I.S.H. Restaurant + Bar, Quattro Pazzi, Boca Oyster Bar, and Wish Café, all in Stamford. As for Hector, he’s the culinary talent.
