Re: Anybody been to Baltimore?
It's a short drive for us, and we're looking at potentially moving there this fall, so I know a bit about the city.
90% of what you'll want to do is in the Inner Harbor/central city area. Plenty of good restaurants in the Harbor, but for my money I'd head down to Fells Point, Federal Hill or Canton Square and take in some Baltimore culture that is a bit less contrived.
For tourist-type things, they have (IMO) the best aquarium in the country down at the Inner Harbor. Also down there you can tour the USS Constitution, and the kids love the Maryland Science Center (also Port Discovery, a hands-on kids museum a few blocks away). The already mentioned B&O Railroad Museum is surprisingly interesting, but the National Museum of Dentistry is not for the squeemish.
Fort McHenry is worth touring, although aside from a few neighborhood places in Locust point there isn't much around it. Baltimore also has two fabulous art museums: the BMA and the Walters. Both are free, and both have wonderful collections.
For shopping and dining, the aformentioned Inner Harbor, Federal Hill (particularly around the Cross Street Market area), Fells Point and Canton are all top-notch. Mt. Vernon is older but has some wonderful (slightly more upscale) establishments and restaurants such as The Brewer's Art (highly recommended). Little Italy is an honest-to-God Italian enclave, with many Italian restaurants that range from "pretty good" to "mediocre".
Hope you enjoy your trip.
We'll burn that bridge when we get to it.
