A luxury restaurant (elegant, good looking, or with a great view) but not soo expensive, any idea?

I need to take someone important to an elegant dinner in September/October in Tokyo, as I promised long ago, because I thought I would have the money by now, but I've failed

I am unable to cancel, reschedule, or modify the plan.

I understand if I don't get any comments lol

But thanks in advance.

Budget: less than 60,000 yen for a course
