We would like to come as a group. possibly 15 persons. can you handle this. and can we start with lunch at the restaurant than the museum tour. thnaks.

It wasn't crowded. It sounds like no problem from what I observed! : )

Agree with Theresa & Christine

Restaurant had outdoor and indoor seating. The servers and cook were great when we went so as Christine mentions you should be able to move tables together for a large group. We had 5 people and it was no problem. You place your order at the entrance with the cashier and then they give you a pager so you then find your own seating while you're waiting for your food. We went to the museum for the Disney exhibit which required timed entry tickets, but afterwards the rest of the museum was open and wasn't too crowded.

I think it should not be a problem. There is space and multiple exhibits. It looked like you could put tables together at the restaurant too.
