Restaurant with consumption bar option?

I know this kind of question has been asked several times, but I'm curious if anyone has any insight on restaurants that do private parties that specifically have a consumption bar (meaning each ordered drink is added to the host's final bill). I am looking to host about 100 people for a dinner and most places do drink packages / open bar priced per person. Most of the 100 people do not drink, and I think it would be the more cost-effective way to host dinner. Any advice or input would be greatly appreciated!
