The menu at Yia Yia Mary's Greek Kitchen (4747 San Felipe, 713-840-8665) doesn't even hint at all the joys in store for the customer who orders its pistachio ice cream ($3.25). It just says "pistachio ice cream." Yes, you do get two huge scoops of pastel green goodness, each about the size of a baseball and chock-full of crunchy pieces of nuts. But this dessert is made even more special by its flaky phyllo cup dusted with powdered sugar, and the extra crushed pistachios sprinkled on top. Be sure not to overdo the hummus and pita, and you'll have room for this surprising treat.
