I was told these are called (translated that is) "Urinate Prawn" or "Pissing Prawn"
Nothing scary in this restaurant, just the regular live fish, prawns and crabs. And all the seafood looked very fresh and healthy. The tanks were really well maintained so I didn't feel AS guilty eating them hahahaha!
We had pipies
And Peking Duck
We also had other dishes but I failed to photograph those. Food was fantastic here and I think we ended up coming back 3 times in total in 5 days. Twice for dinner and once for yum cha. Ooo and they also put on a show for diners too - hand made noodle performace.
