Ocelot was quite good when GrjApp and I went there (~2019)

can also recommend Ono Brewing in Chantilly from a couple visits (one with DELee) around the same time … iirc they have a self-pour pay-by-the-ounce tap system

a bit farther afield is Ornery Brewing in Gainesville; based on a meetup with a former co-worker at their Fairfax location, I’d say it’s well worth a try

Mrs767 and I arrive IAD on Thu 31 Jul ~430p; we could perhaps be persuaded to make a stop at one of these venues to let traffic die down before we set off on the drive to RIC
