Time Out says
Some of the “rules” at Mr. Yogato are as follows: Sing “I’m Too Sexy” by Right Said Fred while you order you frozen yogurt and get 50 percent off, stump the owner on Seinfeld trivia or recite the battlefield speech from Braveheart in a Scottish accent to get 10 percent off. This zany shop also has an old-school Nintendo Entertainment system and oodles of board games. Oh, and frozen yogurt. But you’ll probably be so distracted by everything going on around you that you’ve forgotten why you came.
