Side Street books is a terrific, little book store right outside the center of Patchogue's "Four Corners". You can find everything from new releases to used books here. They also carry other forms of media, including magazines. As a matter of fact, Side Street Books is the first store to actually carry Teen Trend Magazine!
Diane, the owner, is very nice and extremely helpful. The store is rarely crowded, and there is plenty to look through to shop for. Parking is in the back, and is plentiful.
