Let me just jump in here

My little nephew used to work at the spur during his holidays, and I know for a FACT, that those portions are not rationed, or pre-packed or pre-weighed. They pre-cook the ribs, and then its a whole bunch of this pre-ccoked ribs they throw in these big white plastic buckets, and then as the order comes in they just take from there and put on the grill with basting. They sometimes take a larger piece and a smaller one to make up say 500g or what ever. So don't be fooled and think its 200g... they themselves have no idea how much those things weigh and just guess. Some patrons might end up with bigger portions that has been advertised and some less. Guess its all in the luck.
