I would like to have a surprise party for my best friend there with food drink and a room there how do I go about getting it

Call hotel and ask for group sale rep. Its coolest place in Milwaukee.

A party room or an overnight stay room? Also depends on the number of people you plan on inviting. Contact the hotel they'll direct you to wherever you need to go.

I would contact the customer service and inquire.

Yea, they're known for that, contact the front desk, ask for Mr. Kevin

I would just call the attatched Hotel

Are you looking for a hotel room, or an event room?
