The Pizza Paradiso in Gtown is much better than the one near Dupont Circle IMO.
I've heard both sides of this argument, but the Dupont location loses just because the beer selection at the GTown location is so ridiculously good. Really, better than anywhere else. Don't give me the Brickskellar--they're always out of everything, and everything is bottled. The selection and care put into the beer at gtown paradiso is unparallelled in DC. The pizza is entirely secondary, to me.
I know, I know, beer snobs are just fat bored white guys, but still...
Also, abc, you need to get out of georgetown once in awhile.
