Who in Baltimore makes a great Pimm's Cup?
I'm always looking for a good Pimm's. Had a surprisingly good one at Golden West a while back but they haven't had it back on the menu since. I would check out Woodberry Kitchen--man they have good mixed drinks--and Mr. Rain's in AVAM. They may not have Pimm's per se but they have extremely competent bartenders.

Clementine has a great drink with Pimm's called a Gertrude Stein. Pimm's, lime juice, chamomile simple syrup and lemon-lime soda. I've been recreating it at home all summer and it's filled in nicely for us when we might usually go for a Pimm's Cup. (Even our British friends dig it.)
