49th and Penn has Cafe Patachou for breakfast. Nice corner with a Sullivan's Hardware. That same area on Pennsylvania (42nd and north)and the surrounding areas have hugely expensive homes (think 5 figure real estate taxes) and is a wonderful place to walk with lots of trees. I used to have a 4 mile route to walk and it was wonderful anywhere there. It only gets dicier on the east side closer to the State Fair area(between 38th and 46th) but would still walk during the day.
56th and Illinois used to be around the corner from our house. Drug store, grocery, restaurants, fire station, etc.
Check out some of the new stuff on 54th around Winthrop. There is an Italian restaurant, breakfast place, some new stores, etc.
