Recommendations for a nice restaurant that has a sizable private dining room/party room

Hi there! My siblings and I are planning an anniversary dinner for my parents’ 40th anniversary. We are wanting to do a special dinner for them with 25ish close family and friends. Would love some recommendations for a nice restaurant that could accommodate with a private space. We did sixty vines recently for another event and loved it, but want to do something different. They love food and are avid restaurant week attendees, so we want it to be nice, but reasonably priced. Let me know and thank you in advance!!
