I'm posting to recommend the Rusty Scupper anniversary special that is good for tonight and tomorrow night. It's $19.82 for a "four-course" dinner, and of course it has the added advantage of being one of the truly great locations in Baltimore.
You get soup (ours was New England Clam Chowder which was surprsingly good); salad; a choice of five entrees (seafood pasta; crab cake and filet medallions; crab imperial; rosemary chicken; or salmon); and dessert (a cup of ice cream).
My wife had the surf and turf; I had the crab imperial. The filets were perfectly cooked and more than enough for her (she's saving the crab cake for later); the crab imperial had lots of crab meat and though not the best I ever had still pretty tasty. Also, as an extra benefit, we had a table looking at a great view of downtown Baltimore across the harbour.
All in all, it was a good meal at a great location at a pretty good price. If you happen to have a jones for eating on the water, particularly since tomorrow is supposed to be pretty nice, I wouldn't hestitate.
