Hi ladies - I'm currently married (so, a former knottie

) living in the D.C. area, but I want to plan a party for my in-laws 40th anniversary this coming May. I'm thinking of about 80 ppl, on Sat May 16th, and would ideally love an indoor venue that provided catering as well as the space, tables, linens, etc. Not being from the area, I hoped you all would have some good ideas - thank so much in advance for any advice or help you can give me!
