Bagel palace is a great place to go for breakfast. When I lived nearby, it was almost a weekend routine to go there for breakfast. They also have a good selection of items that you can buy from the deli counter.
Firehook has great fresh baked bread- I especially love the cheese bread. If you show up right before closing, they might even give you a free loaf of bread, as they did with us.
Strosniders is a wonderful hardware store with a small-store neighborhood type of feel. They are always very helpful and seem to have all the items necessary when I am running to the store for some last minute home repair.
