1. Captain Larry's on Fort Aveune in Locust Point for beers, lunch, whatever if you want a real Baltimore bar and not some phony ****hole like Pickles. (No offense, Ryan.)
2. Faidleys in Lexington Market for crab cakes, oysters, beer, etc. Best crab cakes in the entire city, and probably the country. Lexington Market is also real Baltimore. They sell "Swamp Rabbit" in LexMarket, which is really muskrat, and you can see the nasty ******* skinned sitting next to the fish. That's awesome. You could also walk from here to the stadium. Some people might whine about the roughness of the neighborhood, so if that kind of **** bothers you, take a cab. If you walk, on the way back, swing by E.A. Poe's grave on Greene and Fayette.
3. Brunch at Metropolitin Cafe and Wine Bar in Federal Hill. Very good breakfast food/brunch, bloody mary's, atomosphere. Can walk to the stadium from here if you want.
4. Sound Garden Music store in Fells Point. One of my favorite places in Baltimore. Thousands of used CDs and DVDs, both movies and TV shows. Very cheap. You could pick up Season 1 and 2 of The Wire here for about $29 each.
5. Live music at The Waterfront Hotel in Fells Point. Never a cover, usually pretty good bands, cute girls. Not too crowded. They always have someone playing and they book some decent acts. Directly across the street from the old Bmore police headquarters, used in the TV show Homicide.
6. Take one stroll around the Inner Harbor. It's fine, but it's a tourist trap. Duck inside the Barnes and Noble built inside the old Power Plant, just because it's so huge, it's kind of cool. Ignore the rest.
7. Have a nice, classy dinner at "b" in Bolton Hill. b is probably the least expensive resturant in Baltimore that I would classify as excellent, and it's in the middle of a neighborhood. Food is outstanding. If you want something not quite as expensive, but better than bar food, try The Brewer's Art on Charles Street, where they brew their own beer called Resurrection.
8. Brunch or dinner at The Golden West in Hampden. Southwestern hippie fusion, if that makes sense. Everything has green chilies, so don't complain. They won't serve the food without it. The quirkiest, fun casual restaurant in town.
9. The Blue Agave for Mexican in Federal Hill. Best authentic mexican food in the city. Not cheap, but very good. Great margaritas. Check out the rest of the bar scene in Federal Hill too, like Porters, Mums, Mothers.
10. O'Donnell Square in Canton. There are about 10 restaurants/bars here of varying degrees of good. Nacho Mamma's for good Mexican with a baltimore twist (like quesadillas with crab meat in them), although Helen's Garden probably has some of the best food in the city (try the pork chops au poive).
