best place to have a dinner party?

my fiance and i are looking to have a dinner party with anywhere between 35-50 guests depending on who rsvps. we are on a bit of a time crunch as we’ll be getting married the day prior and there is family who’ve already taken the day and bought plane tickets. We’re looking for something that fits a semi-formal dress code and could accommodate us at around 50$ per person. also a huge plus if they actually pick up their phone, respond to emails, and return voicemails!! we are 60 days out from our wedding and just had our original resturant respond to our email saying they rented out the room we had been speaking about. (they took 3 hours to respond when i asked for the deposit link and told me it wasn’t available)

we’re not looking for a venue, just a resturant that can accommodate a rather large group.

thank you all so much in advance, sincerely a VERY stressed out bride to be
