Restaurant Recomendation for 50th Anniv. - rent entire space

Hello, my parents are having their 50th anniv. next Feb on a Saturday night, and we are looking for a place to celebrate. there will be about 125-150 people invited.

Currently we are looking at a few hotels, one is the LIberty hotel. They are extremely expensive and also I thought that reserving a full restaurant instead for a banquet room at a hotel might be a nicer experience.

Could anyone recommend a restaurant that could hold 125-150? I would be looking for a place on the same level of the LIberty hotel or somewhat close to that.

Thanks in advance
