Where to hold a private party?

[ariwriter.livejournal.com]

Can anyone suggest a restaurant/bar in the general area that could host a small cocktail party of 20-30 people on a Saturday night? Guests would buy their own drinks, but I would ideally purchase (through the restaurant) about $100 in simple appetizers. A private room isn't necessary. I can deal with Redline's prices in Harvard Square, but am looking for something more convenient to the Davis/Porter/Inman areas.

Would Orleans be able to handle this? Or PJ Ryan's, even?

Thanks!
