I’ve been meaning to try Call Your Mother in Dc but never got around to it so I was very happy they opened closer to me in McLean! My friend and I went around 10:30/11am on a Saturday and there was a fairly long line. The line goes pretty fast but we did have to wait about 20-30mins for our bagels. Definitely longer than you’d expect at a bagel shop. BUT very good quality bagel sandwiches—we were very satisfied. We got the pizza bagel and the thunderbird. The truck is super cute. I would go back as I think they have the best bagel sandwiches I’ve had but I definitely wouldn’t go when I’m starving because I’d anticipate a wait.
