I planned my 10 year HS reunion and we had it a Joe's On Weed in 2005 (so my recollections of specifics are a tad fuzzy but I will do my best here).
Joe's is not a place I would normally frequent, but their size (we had a class of 300 and ended up having nearly 300 attendees with spouses) and willingness to work with my requirements made it perfect.
It was on a Saturday night. I think it was from 7:00- 10:00.
The committee wanted a casual place where people could wear jeans and just hang out and catch up. We weren't into the cocktail attire and dancing idea.
I didn't want a cash bar. There were definitely some hors d'oeuvres...typical sports bar kind of fare...but we specifically told people that there would be no dinner so most people went to dinner prior.
Our big stipulations were:
An all you could drink package of beer/soda.....but maybe wine and well drinks were included
No room rental fee (we didn't want to front any money, but I did sign a contract and secure the room with a personal CC)
Keeping it at $40 pp or below (but I honestly don't remember what the cost was...I think $40...it was 4 years ago)
and the most important one for me was:
Having the venue collect the cash at the door. I didn't want anyone to get the impression that anyone but the venue was making any sort of profit off of our class.
The staff at Joe's was fantastic, as a professional event planner, I would definitely work with them again if I needed a space like that. They have a DJ booth as well as a stage for live music. They let us use their microphone for some announcements with no AV charge.
I would definitely give them a call to see what they can do.
Or if you want suburbs (with that size group) and want to spend a little more cash I would call Maggiano's.
