Few can compare to the classic plump burgers made in America, but Flippin’ Burgers certainly comes close, at least according to anyone who visited this celebrated Swedish eatery. “It has the best tasting burgers for the whole family,” says Lisa Sandefeldt. “Its milkshakes will have your kids stay put for as long as it lasts.” Many also praise its casual setting, reminiscent a ’50s-style dinner.
