Do you have a private room for parties of 50 people?

Yes

This location does have a party room. It will require xalling ahead (usually 10 days) to reserve it

They should

It does depend on the location. The one in Glendale Heights does not, however Niles, Downers Grove, and I believe the Skokie one as well do.

Call. They book up fast.

Yes. Yes they do.
