Pancake stack and smashed-patty burger favorite Diner has opened a second store, and they are moving on up! This time, instead of a former convenience store on a busy intersection, they have brought their diner-fied menu to the rarefied halls of Plaza 66. Yes, Plaza 66. Fifth floor. Because nothing says luxury shopping like a big ol' mac and cheese and a milkshake. This is Diner's first move outside their original location but it's not their last. Rumors around Shanghai suggest they have already signed a third space in a downtown mall, though it's probably too early to blow up their spot like that. In due time. In the meanwhile, if you can't be bothered to cram into a booth with two strangers on Wulumuqi Lu, there is now an alternative.
