Party venue ideas for 30-50 adults?

I’d like to throw a party at my house for my professional networks and I’ve gotten vetoed by my spouse. She said no primarily to the venue being our home.

I was trying to think of fun, casual places to host this party, and could only really come up with a few restaurants that I know have private rooms or hotel conference rooms.

Please send me your suggestions for a place that can fit 30-50 people—I’m also trying to avoid super expensive options, which is why I suggested my house originally. Thanks, y’all!
