Elmerr, You can contact me directly if you like by clicking on my name to the left. Just curious where you are staying and what dates you will be visiting. I live just up the street from the Hopkins campus.
Chezkatie has put down some great suggestions. My favorite all around for breakfast is JIMMY'S in Fells Point. It's on Broadway just above Thames St. Once you get in the neighborhood anyone can direct you. It's the most Baltimore. BLUE MOON is just west of Broadway as you approach Fells Point and may be better for you. It's funkier and popular with the college crowd.
Still with breakfast, there are 3 places in the Hopkins area I would recommend.
PETE'S GRILLE at 32nd and Greenmount Ave. Just a few blocks east of the campus, it's counter seating only but pretty cheap and the home fries are very good.
MISS SHIRLEY'S on W. Cold Spring Lane at Keswick Rd. This place is new and I've only stopped in to have a look. Southern inspired, the prices seem on the high side, but lots of ambience. For fast and simple, there's a SAM'S BAGELS just across the street, also one a block from the campus at 32nd and St. Paul St.
CAFE HON is the homiest place. On the "Avenue" (W.36th St.) in Hampden. This is John Waters territory. Sit at dinette tables like you did when you were growing up, with oilcloth covering the tables. Everything is good here, and even better at lunch and dinner. This is just minutes west of the Hopkins campus. You can't get more Bawlamer, hon. (FYI.... Hon is an affectionate nickname for most everyone in town, but is most properly used by veteran waitresses as in "What can I get you, Hon?"
For lunch and dinner there is ALONSO'S, just across from Miss Shirley's on W. Cold Spring Lane and same ownership. It's bar food, but good and the giant hamburgers are legendary.
Lexington Market is certainly worth a visit at lunchtime, but the neighborhood might put you off, even though it's perfectly safe. You'll find anything you want at the various vendor stalls. FAIDLEY'S is the crown jewel of the place with their backfin crabcake and raw bar. It's stand up only. The great shrimp salad sandwich that Katie mentioned is from MARY MERVIS Delicatessen in the Market.
I'm sure you will stroll the Inner Harbor at Harborplace, and you really can't go wrong anywhere. CHEESECAKE FACTORY is the most popular place and if you've never been to one, it's certainly worth checking out. Likewise for seafood you can't go wrong at LEGAL SEAFOOD just across from the Gallery at Harborplace or MCCORMICK & SCHMICK at Harborplace as M&S GRILLE or on Pier 5. PHILLIPS is the place for tourists
In Little Italy at 321 S. High St. you will find AMICCI'S www.amiccis.com
a very informal place for huge portions of very good italian food. The house specialty is the Pane Rotundo, a hollowed out toasted bread bowl loaded with jumbo shrimp in a creamy garlicky scampi sauce. Add a salad for a simple full meal. In the current issue of Baltimore magazine they were named one of the best places for "Cheap Eats" and the annual City Paper Best of Baltimore issue, just out last week, named them "Best Italian". College kids love this place. Open for lunch and dinner.
East of Downtown in the hot hot hot Canton neighborhood on Boston St. at Clinton you will find the new CANTON'S PEARLS, where the jumbo lump crabcake is getting rave reviews. I haven't been here, but it's on my list. This would be for dinner.
Also for dinner I would highly recommend PAZZA LUNA in the getting hot Locust Point neighborhood on Decatur St. and Clement just off Fort Avenue as you head to Fort McHenry. It's an italian inspired menu with the motto "In Garlic We Trust", but the crabcakes & steak are excellent and the decor is a real treat if you like Sinatra and the Sopranos. It's a virtual shrine. Kim, the owner, will "HON" you to death. You'll feel like you're in her kitchen. Reserve at 410-727-1212. Closed Sunday and Monday.
You can't go wrong at any of these places. Let me know if you need more information.
