In 1995, he moved to Colorado and opened Fanatics Sports Caf in Boulder which he sold and then became the Managing Director of Trios Grille and Wine Bars in Boulder and Denver. Gitlin's goal is to continue founder, Teresa Taylor's, vision of making Nissis the premier live music and dining destination in Colorado.
Though not considered a bar, Nissis award-winning bistro serves specially selected wine, beer and a limited cocktail/martini menu, along with tasty, gourmet "small plates" dinners, from Bacon-Wrapped Scallops and Filet Mignon to Seared Ahi Tuna. Nissi's chef-prepared cuisine was awarded "Best Restaurant" in Lafayette, Louisville, Erie and Superior in 2006. Nissi's also features decadent desserts and after-dinner drinks. John Lehndorf of the Denver Post says, "Nissi's is a delightful 21st century Ricky Ricardo supper club."
