Located on Steamboat Wharf in downtown Mystic, the Green Marble has been a favorite meeting place in the community for years. Serving freshly roasted coffees and teas, a menu of bagels with different toppings, bagel sandwiches and soups are offered. In addition, cookies, cakes and muffins are available for those with a sweet tooth. A large selection of whole bean coffees and loose teas are sold by the weight.
