We stopped by the Lufthansa Business Lounge (DC Dulles Intl, Concourse B Airside - the lounge is located near Gate B50.)
We used our Priority Pass for access. We were there around 2:00pm. There was one other person there when we arrived. (More folks joined us soon after).
They served some really nice cold cut sandwiches. A wrap of some sort. Pretzels and mustard. Vegetarian stew (DH said that it was pretty good). They also had some desserts set out, but we didn’t try any.
It was a nice quiet space.
