Is there room for a birthday get together of about 15 people and how does work for food and drinks ???

Yes, plenty of room on multiple levels.

Yes you can make reservations in advance for the party. The food and drinks are unlimited all you can eat and drink mimosas. I went at the beginning of November and it was $72 per person and you get the table for 2hours.

Yes , call ahead because they be crowded they put tables together for large parties .
