The proprietor of a planned new pizza joint called Za in Broad Ripple, Michael Keenan, says he has enlisted an all-star cast to develop his pizza recipes: Chef's Academy Director Tony Hanslits developed a traditional tomato sauce; Meridian Chef Dan Dunville developed a sweet tomato sauce; and Rene's Bakery owner Albert Trevino is on dough duty. Za will offer a basic menu of slices of pizza, whole pizzas and breadsticks. Keenan, whose family is from the East Coast, said there's room in Indianapolis for a good pizza-by-the-slice restaurant. He hopes to open the first or second weekend in June in the former home of Slinky, a women's clothing store. Keenan has an option to expand into the spaces above the shop to allow for a larger dining room if business takes off.
