They're known as the best crab xlb. For the simple reason that most places don't do pure crab
From left to right, crab meat, crab roe, crab gao xlb. No pork at all. As such it looks very flat because there's no binder so the filling doesn't remain as a ball, unlike normal xlb
Skin doesn't pass tho. Each has it's distinctive flavour which is V good, which is halfway to being impressive. The crab meat esp is quite interesting, it actually tastes kind of like meat, very unique and v diff from what you expect
Worth a try if you're nearby, maybe it's just not the right season
