chateau blanc

"White Castle" translated into french. Used to trick your date into thinking they'll be given the "wine and dine" experience when you're really planning on offering cheap, greasy onion rings. Might work to your advantage if your date has a sense of humor.

I told her I was gonna take her to chateau blanc. The look on her face was priceless as we walked into white castle, overdressed for the occasion, and ordered a crave case.
