The Bistro Burger guys have opened up a spot on Hengshan Lu that's looking to move a little away from the "burger" and closer to the "bistro." In addition to a few nods to the original, they've got some seafood, some hot-dogs, some salads, some steak. Just an all round more balanced fare landing on the plate. Expect to hand out about 100rmb if you're sticking to the burgers and 'dogs, 200-300rmb if you're going for varying degrees of surf'n'turf. They have a very pretty rooftop terrace.
