10.WestburyMost would include Vincent's Clam Bar or The Trattoria as their favorite Italian place on Long Island, but my favorite is a lesser known one called Tesoro in Westbury. The staff always treats you like family (which isn't unusual for Italian places, but I feel they do an extra great job at that) and the food is the best I had relative to Italian cuisine.Veal Castagna9.HicksvillePicking a place for Indian food can be overwhelming in Hicksville with all of the options, but New Chili & Curry stands out as the best. Always a wait, but worth it. You can get great Indian food elsewhere in Hicksville, but none are as good as New Chili & Curry.Mango Chicken8.Roslyn, Babylon, HauppaugeI can only vouch for the Roslyn location, but I've been to maybe 100 sushi places on Long Island and Kotobuki is the best. The fish is always fresh and delicious and they offer a variety of unique rolls. You can't go wrong with any roll you get! Only downside is no reservations and a long wait.Puff the Magic Dragon Roll7.GreenportGreenport is a popular tourist destination which results in a bunch of dining options in the area. Many are "tourist traps", overpriced, and not great, but Noah's stands out among the clutter of mediocre dining options. I've heard that service here isn't great, but I've always had good experiences with the wait staff and always have found their food to be delicious.Lobster Mac and Cheese6.HuntingtonAn always changing, but always delicious menu of small plates. You're lucky that they offer small plates because when you come here you're going to want to get a bunch of different options. They also have a great selection of beer.Crispy Calamari5.HuntingtonHuntington is the best town for dining options in Long Island and Vitae stands out as one of the best restaurants in the area. Delicious food and great service - you can't go wrong with any dish here. They aren't a steakhouse, but their steak is better than any steak I've gotten at a steakhouse.Filet Mignon with Bernaise Sauce4.Massapequa ParkThe opposite of fine dining, but Smokin' Als is the best option for delicious BBQ on Long Island. Their meat, sauce, and sides are all delicious and it's rare you won't walk away with two days worth of leftovers. Sure, there are better options in the south for BBQ, but when it comes to the Long Island (and NYC), you can't beat Smokin' Als for BBQ.The Big Melt with Brisket3.Great NeckGreat Neck is known for having a ton of Asian restaurants (especially sushi), but the best dining option in the tow is modern American at Lola's. Lola's offers a variety of small plates and entrees that are unique and delicious. The chef / owner has his own duck farm which results in a bunch of delicious duck options.Brussel Sprouts (the best sprouts you'll ever eat).2.Garden CityFor out of this world mussels, you can't beat Waterzooi in Garden City. I've had all of their broths and they are all delicious. The garlic mayo that comes with the frites are addictive. This place has probably the best Belgian beer selection you can get on Long Island as well.Creole Mussels1.Roslyn & HuntingtonBesito offers absolutely delicious upscale Mexican and the best table side guacamole you can get it in Long Island. This, along with their extensive tequila menu, great drinks, and great service, puts them at #1 on the listBudin de Mariscos (Tortilla Pie with Shrimp)
