The menu at Port Authority is half vegetarian/vegan and half carnivore. The chef, who is usually a pretty pleasant guy, is a vegetarian. The veg offerings are eclectic, international, and usually very good. He changes the menu pretty often too, so you can try new things. I have sometimes had meals that haven't been that good for me, as I don't like spicy food, but others have been very good. Read the menu and order carefully. I do recommend the veggie Reuben. We eat there about once per month.
Cons: Sometimes not good!, Small with not much atmosphere
