Friday at Alonso's: Stillwater Stateside Saison firkin.
Thursday at Pratt Street Ale House: the debut of their "Channel Crossing" joint Stillwater/PSAH project, tapping at 6 PM.
Thursday at Metropolitan--some firkin TBA (well, if you go there, it'll say on their "coming firkins" menu board). Also cask night (and Flying Dog Night) at Max's, and firkin night at the soon-to-relocate Frisco Grille in Columbia.
Incidentally, Max's has just dramatically revised and updated its website. Now the beer list looks reasonably up to date. And this just in via e-mail:
