Starting next week, dessert lovers will have a trendy new spot in Tremont at which to score all matter of sweet and creamy treats. Battr (910 Literary Rd., 216-202-6157), opening in the long-vacant building next to the former Lola/Lolita space, specializes in Belgian waffles, Hong Kong-style bubble waffles and French crepes. Those products are then filled, glazed and topped in a variety of ways.
