I stopped at JB's Deli this weekend (5501 N. Clark) to buy some bagels from NY Bagel & Bialy. They were selling half dozen bags of day old bagels for $1. The fresh bagels were only 55 cents, about a quarter less per bagel than I usually pay to avoid driving to Skokie (at Beans & Bagels under the Brown Line el tracks on Montrose).
While there, I tried a couple of cheese blintzes from their deli case. They had cheese and blueberry, both of which looked good. Even microwaved (so I could eat them immediately) the cheese blintzes were delicious.
The deli is built into a pharmacy so it's kind of an odd setup. The people were particularly friendly and helpful. I'll definitely be back to try their deli sandwiches.
