Duck fat fries. There really isn't any reason to order anything food item(unless you care about your cardiovasular health).
Okay...maybe that isn't entirely true, I enjoyed my chard spaghetti, with carrots, red chilis and a white wine sauce. My friends seemed pretty satisfied with their various pizzas (except my friend that got the duck rhubarb pie, she was grossed out and disappointed).
You might also want to wash down your fries with a beer from their extensive menu.
But really, focus on the fries...few potatoes can compare.
