Maggiano's in Tysons has a party room and different food packages - not sure if you can get only appetizers and drinks or if you need to order entrees too.

I'd also look at Clyde's in Tysons.

Red robin which is like a TGIF chain has a party room. I've been to a shower there with about that many people. Can be kid friendly

Joe's Pizza has a pizza buffet and salad bar. Very family friendly.

We're looking for a kid-friendly place that can accomodate 75 or so people for an afternoon party with light appetizers and drinks. Something like a reception but really informal -no decorations, etc. Just want a place to get all our friends and family together at one time. NoVa would be ideal but we're open to DC Or MD too. Hoping not to spend a crazy amount. Thanks in advance!
