No, there is no viewing from the plaza restaurant. It sits in too far (ice cream parlor is on corner) and the very limited window seating would only provide maybe a glimpse over peoples heads and somewhat far away. I would suggest Tony's Town Square and if you're lucky, you may get a porch seat (not guaranteed but ask). They have no problem with letting you linger at the end of your meal to catch the parade. They will even prevent people from standing in front of you on the porch. I've done this twice now and it's great! You are somewhat elevated up on that porch and the angle is great for seeing it come around town square.
