Not sure what your budget is, but we just did a family meal of 16 in the private room at the Palm in Tysons. Worked out very well for us.

Hi! My extended family is coming to the DC area in the spring for a mini reunion and to see our new baby. We live in Chantilly, and have been asked to find a restaurant that has a semi private dining area that we can all go to. Can I get suggestions? Thank you in advance!
