All the terminology on fancy restaurant menus can be overwhelming. From Judy Wu at Gaper's Block,
a glossary of common menu items and terms.
Gluten-Free: This dish contains a small trace of gluten, but a full dollop of bullshit.
Duck Fat: Duck fat fries, rillette, popcorn, confit, Brussels sprouts -- never skip this menu item.
Amish: This chicken was raised without electricity and fear.
