I am getting married next Labor Day weekend on Sunday and need a large Rehearsal Dinner venue in D.C. for Saturday night (which we realize is a lot to ask). Our guests are going to be staying near Dupont Circle so somewhere withing walking distance would be ideal. We are looking for a venue that can seat 150 for dinner, or at least have a standing reception for 150. We would love something casual with great food, especially showcasing local/Southern cuisine, but we understand that few places will be large enough for our group. I have already started calling the venues recommended by Washingtonian magazine's bridal issue, but could use more suggestions. Thanks!
