I'm planning to book a theater restaurant for my one man show.

How long do think is good amount of time? one hour? one and half?

The restaurant has a small stage which is good for stand up to parlor stuffs.
And audience can be around 30 to 50.

I would like to have some advice for it.

Thank you very much.

Depends on what kind performance you going to perform...is it full illusion or mix with chit chat with the audience, if its full illusion its better an hour max but if its mix better 1,5 hour..
