Class Reunion Venue

Hi all - need recommendations for a class reunion for around 200 people.

disclaimer: yes it sounds miserable and yes i’m dreading it

want somewhere that we can drink but still have some social “outs” if people want to go to a different spot at the venue. something like renting upstairs at Tellus, and people could go downstairs if desired. trying to keep it as comfortable as possible when class reunions could tend to be uncomfortable. TIA!
