Wednesday afternoon.
Arrived at 215PM, lounge was around 10% full. By 330PM, lounge was over 90% full and remained that way by the time I left at 445PM.
Champagne was Lanson.
Dining menu

Appetizer - scallops, pretty good

Main - cod, also not bad

Dessert - cheesecake, this was average, it was also pre-plated, the plate was cold

Buffet, from L to R - broccolini, penne pasta, shrimp, chicken, soup. Also not shown, there was basmati rice.
Having been at the EWR Polaris lounge 2 days ago, the IAD one had better service and food. Crowding remains an issue at both lounges.
