The boundaries between neighborhoods can be fluid (Is the Argyle in Park Slope or Gowanus? Is the new Cobble Hill Coffee Shop in Carroll Gardens?), but we’re pretty sure that the diner formerly known as New College Restaurant, at 224 4th Avenue, isn’t in the South Slope. Still, after renovations, the restaurant re-opened as, well, “South Slope.” Here’s a description from Brooklynian: “They have broken through all the dim outer walls on that corner and created a lovely open space with sliding glass doors, similar to the look Beso had on Union and 5th (before is closed last year). Menus still lay claim to their history of ‘serving Park Slope for 25 years,’ but from the looks of it the owner just decided to revamp the spot with a perhaps hipper name and contemporary look.”
