I thought this was really clever... That's the menu in white in the middle. When you approach to read, you're sprayed with a soothing fine water mist. So naturally, you want to stay, and read more, and more, until you've overstayed your welcome and it's time to go in and be seated... The sprays went off at random about every two minutes.
Beneath the menu it says, "Sunny and sheltered. It doesn't commit you to anything."
