I was just talking to [redacted] about this last night. He said that they've had plenty of requests and that this has been a long time coming. In fact, he mentioned when he interviewed with GWU, they honestly wondered why people had been requesting Seattle, as they felt there was nothing going on there.
Love how Grubwithus is slowly launching into cities. I think it's a great marketing strategy -- even though it leaves some space for competitors...
