Screw Fishtown... Kensington is the next place to be. Of course when it gentrifies more it will get "subdivided" into mini-neighborhood names because the residents (or RE-AHL-TAWRS) will want to distinguish themselves.
Problably North Kenso, South Kenso, East Kenso, West Kenso, South Central Kenso, Southeast Kenso....
Yours truly has been keeping an eye on rentals in that area; leaning towards buying right now... but want to be very close to the El.
