this restaurant was previously known as Oshin. i've probably only ever been to it once (if ever), and have always had the impression that this was a pricier place. having said that, their buffets don't sound too bad in comparison to the others on this page.

"for tables of six or more all-you-can-eat banquets are available" - there's no further info on their website about this, but i asked by phone and was told it is a $24 per head menu featuring a selection of entrees, breads and mains (the most popular ones) from their menu
