Rachael ate this @ Moon Bell Restaurant 月铃菜馆
Comes in two sizes, either u choose big / small.
Small will be lamb shoulder, big will be somewhere near the thigh.
Took some time for them to roast the lamb but its worth the wait. Roasted lamb was sprinkled with chilli powder and it came with the dark dipping paste (the same one for the duck with pancake). Ahhh...craving for that now. Slurrrppp
