For cake/sweets buffet with time limit usual but a few exist.
Search again at Google by "ケーキ 食べ放題 無制限".

食べ放題(tabe-houdai) : viking
無制限 : no limit

2)
Never heard/seen such coupons.
For some off price usual.

Do you know any viking restaurant In greater Tokyo area where I get Lunch Buffet for less then 1000円.I use Tokyo wide pass.

I'm not quite sure what a viking restaurant is, but a buffet for less that 1000 yen is probably impossible, if there is one, I would like to try it.

Here is a link to a list of Buffet type restaurants in Tokyo, however, you won't find many or any for \ 1000.
