After a 12-year run, upscale Italian restaurant Bertolini's has closed its Circle Centre location. The restaurant, on the first floor of the mall next to P.F. Chang's and Champps, was part of Chicago-based Morton's Restaurant Group. The company, like most upscale chains, has struggled in recent months as the economy flounders. In a statement to IBJ, Morton's said the local restaurant wasn't profitable. Bertolini's still has two locations: in Las Vegas and King of Prussia, Pa. The Circle Centre space doesn't have street access, but with exterior signage it could be a great location, said retail broker Steve Delaney. What sounds good for here?
