Baltimore is a great city......off the top of my head
Hamden (really really great food there too!!!), Elliott City, Cliburn Park is better than Druid Hill. Patterson Park has a great Pagoda, Evergreen House

We have a nice Zoo and many many GREAT Museums BMA, Walters, Visionary Arts Museum is cool, weird and fun
Best Pizzas matthewspizza.com/
It's crappy location near Patterson Park and the pies made with Lard ;-) its amazing and so Baltimore
The Harbor is not the best place for food ....its a little touristy
Try G&M
https://gandmcrabcakes.com/ for sea food, good value and real Baltimore clientele not the best best Crab Cake but many folks like it.
Are you thinking of trying Steamed Crabs? Jimmies Seafood
http://www.jimmysfamousseafood.com/ very local IMHO hard crabs are too expensive go for the crab cakes...less trouble.
My family and I like:
https://pappascrabcakes.com/restaurants several locations family owned great food and one of the best Crab Cakes going
