They have A LOT of different types of biscotti. They even have ones for your dog.
I tried the cranberry pistachio, which was good. But the only thing is - it gets stale really quickly. I tried a bite right after a bought it and it was baked perfectly - crunchy, but not hard to eat. When I went to finish the rest of it a couple of hours later, it was already kind of stale, which meant buying some to bring home was not an option. So if you do go to Enrico's, my advice would be to enjoy the biscotti immediately!
