June 20th, being a Thursday, is not typically too busy during Lunch 11a-3p. There is a lunch pop around 12:30p-2pm, but a party of 10-12 should not be a problem.
It's not usually crowded. There is a parking deck across the street underneath the building at Monroe and 7th.
Parking is very hard to find. I had to park at the kiss a d ride at the brookland metro station and walk over. (Very short walk) I don't remember any long tables. I did sit outside. They were crowded at dinner, so I'm thinking they would be at lunch as well. They do host large groups.
