Recommendations for restaurants with a small private dining room

Hey everyone,

I need your expertise.

My dad wants to throw a celebration party for my mom's 80th birthday next month. The party size will be around 18-25 people and he would like to keep the costs at around $40 per person max (fixed budget of $1k).

I figured the easiest course of action would be to find a restaurant with a private dining room since they don't have the space to host a party that size at their home.

They are open to many cuisine types and the location isn't a factor as I just want to present them with options and let them decide.

So if you know of any restaurants with a small private dining room that costs around $40 per person, I would appreciate your help listing them below.

Thanks in advance!
