Yep, hope it helps. I'm planning a wedding so I am all too familiar with catering costs and restaurant spaces (not this region). With inflation, these costs are much higher than they were even a few years back.

Since it's a brunch, one idea might be to find a meeting space like others are suggesting and then cater something in like panera. That might not fit the vibe of the event you are planning, though, but it will avoid increasing the budget or cutting attendees. A thread here the other day was discussing affordable caterers.

Make sure to find out things like food minimums, venue tax Providence might tack on, and whether the location you want to meet only allows you to use a certain caterer for this event.

Good luck.
