Hello! I'm looking for a place to host a casual coffee/pastries-ish work event on a Saturday morning near the DC Convention Center. Could be a group around 50 people (not all at one time). Don't need full private space - but would need to be able to stake out an area where employees could meet/greet and have access to the food. I'm trying to avoid paying an arm and a leg for a donut at the convention center. Any suggestions?
