"Not as much shopping as 125th, but not so bad :)"
From Riverside park to Broadway, there's not much there other than apartments. From Broadway to Amsterdam, there are quite a few shops and surprisingly a liquor store that stocks decent wines (this is on the south side of 145th). From Amsterdam to St. Nicholas, there is a raw food restaurant, which is quite good, if you like raw food. There is also a new Starbucks, and a Pathmark which has parking around the corner - if you show your receipt from the store, the charge to park in the parking lot is $1. The parking for Pathmark is very nice. It has a direct, inside access to the store and is within a building, with good parking attendants. Also in the same area, there are two new banks and an apartment building that has been renovated. If you go to City College you should know that City College also has a shuttle bus that picks you up from the 145th street subway on the southwest corner of 145th & St. Nicholas & drops you off at the center of campus at 138th street and Convent. Past St. Nicholas on 145th street, the neighborhood changes and I wouldn't walk there unless you have reason to be there (like you live there.) 145th street widens as it gets closer to the 145th street bridge to the Bronx and there are two gas stations very close to the bridge on 145th. The Bx19 runs on 145th street and surprisingly runs on time.
