"I just ate TEPPANYAKI here in Changzhou... all you can eat & drink.. take as long as you like and they keep telling you it should be interpreted as " endless". Sushi / all sorts of tuna / octopus / grilled fish and excellent fillet & other steaks.. cooked right in front of your at your table. Beer / hot saki.. you name it. 17 quid....... I ate about 200quids worth at london restaurant prices & the staff were great.
Restaurant name is TAIRYO & they have one in shanghai"
If you're vegetarian, I suppose you could still achieve a bargain on the all-you-can-drink part. Sadly, or perhaps happily, my own days of gorging are over.
