We managed to catch a great meal at Marti's Restaurant, Bakery and Spirits by the Inn overlooking the Yakima River. It has an in-house bakery, an excellent Sunday brunch, a shining salad bar and delicious food. Busy place. (For fast-food afficionados there's a McDonald's in WalMart nearby, and a Burger King nearby).
Buy a baked goodie, bread or a pie before you go.
