I see you said E.P. If it's nice out, id check out the East Bay Bike path area for a walk and maybe the area around Borealis coffee.

The downtown bridge is nice, there is quite a bar/brewery scene in the armory neighborhood that's more recent.

Federal Hill is nice and I'd swing by Pastiche (their chai vanilla lattes are basically the best hot drink in the city). You can easily walk between the main points on Westminister, Broadway, and Atwells very easily since you're not driving.

Check out the small businesses on Hope and Blackstone Boulevard.
