If you think hotel resort fees in Las Vegas are sneaky, be on the lookout for odd restaurant charges that go by official-sounding names but all add up to one thing: additional profits for the owners.

A handful of bars and restaurants along the Las Vegas Strip tack on fees variously called a “concession fee,” “venue fee” and “CNF,” which can amount to as much as 5% of the total bill. They’re often spelled out in tiny print on the menu, crammed alongside the mandated warnings that consuming undercooked meats and seafood can be dangerous to your health, but you may not notice them until you get the itemized receipt.
