Not a lot of time to go into detail, but if you happen to be reading this before heading out, I'd recommend the Widmer Babushka Stout (burly, with the berries adding just a minor key), Hair of the Dog Jim (huge beer, super intense, rich, spicy, bourbony, amazing), and Dupont Avec Les Bons Voeux. I'd skip the weedy Lagunitas Black Pepper Stout.
Also, the upstairs seemed way less crowded in the early part of yesterday's visit.
