After a "business dispute" temporarily shuttered the Tremont Street location of UBurger late last month, it now seems to be closed for good. A reader tweets a photo of a sign on the door indicating that a restaurant called Ziti's Express is coming soon. The downtown location is right by the Park Street and Boylston Street T stops.
UBurger, a small local chain, also has outposts by BU West, in Kenmore Square, and by Northeastern, with an Andover location on the way.
