Quiznos closed its location at 1545 E. Belt Line Road, Richardson, in March. A sign in the window thanked customers for their support but confirmed the business was closed. The sub shop’s offerings included soups and salad for lunch and dinner as well as hot toasted subs all day. The closed shop, which has been removed from the Quiznos website, was the chain's only location in Richardson, though it does have locations in Plano and Dallas. www.quiznos.com
