LAKE GEORGE With many businesses closed for the winter, merchants in the Mayard Center are planning to stay open this year. Tom Mastrodomenico, owner of Pizzeria Mangia, said he was open last winter, and is doing it again this year. It was all right last year, he said. You have to grow your business, one pizza at a time. His next door neighbor, Reginas Full Service Salon, is no stranger to year-round business. Ower Regina Wells has been working all year for seven years in her Mayard Center location. Mastrodomenico said that the Perfect Blend Cafe, a coffee shop, is open Thursdays through Sundays, its first year of year-round operation, and Sports and More is open on weekends and by appointment. Sports and More has gifts and apparel for the sports enthusiast. The Tom Tom Shop has been open all year for as long as I can remember, Mastrodomenico said. The Tom Tom Shop has a large variety of gifts, cards and souvenirs. The Patriot, a military museum and retail outlet for military memorabilia, is open by appointment this winter.
