Search Foursquare for Restaurant Secret Menus
A quick search for “off the menu” in my neck brought up some treats that matched the phrases “secret menu”, “off menu” and “off menu”: a drink called “William Blake”, truffle burrata, cauliflower appetizer … and other products that Foursquare users have rated as the best in these establishments.
As with fast food secret menus , this might be random or missing depending on your server and when you go, but it doesn’t hurt to ask.
USA Today has a list of top secret menu items at 10 restaurants nationwide.
