Is this restaurant family friendly? (Not gonna be traveling with family per se...just a group of around 10-11 seventeen year olds and wanna know if the environment is appropriate).

Yes.

Thank you very much

Yes, however you should call ahead so there won't be a wait.

It's a fairly laid back environment. I'm sure they could accommodate that large a group. (Maybe give them a bit of notice?)

It is very much so

Yes, should be fine.
