Charm City inner harbor recs?
chazzerking: checking your profile (I have an aunt from Hayti) - you're prob. familiar with STL's The Hill (no relation) and B'more's Little Italy is sort of similar (I loved it on a recent visit) but that gives you an idea of what to expect, old-school red sauce (which was exactly what I was looking for) and tidy houses with scrubbed steps and BVM in the window.
Cross Street or Lexington Market - both great choices for lunch grazing.
if you find yourself on Federal Hill a nice post lunch walk is up to the park - try not to get vertigo while imagining the slope covered in snow. stunning view.
The Blue Moon Cafe in Fells Point is a must for breakfast. There isn't a bad thing on the menu, it's cheap, and enough food to keep you going for all three days of your trip. Oysters and huge draft beers at Cross Street Market in Federal Hill. If you're a beer fan, hit the Thirsty Dog Pub while in Federal hill. They brew their own and it's something like 2 drafts for $2, the pizza is pretty darn good too. (Although I've always had a few while eating it.)
La Scala or Amicci's in Little Italy are decent but other than that stay away from the other places there.
The Black Olive in Fells Point is good, but it has been awhile since I was there last.
Citypaper.com is the local "artsy" newspaper's web site and they by far have the best restaurant reviews.
It's kind of late, so if I think of any must go's, I'll post again later.
