Did I do good for breakfast?

Okay, my family went to this mostly unhealthy place (it's actually an ice ream diner) for breakfast. I got a small bowl of old fashioned oatmeal (not sure how it's old fashioned) which came with milk and brown sugar on the side, which I didn't use. I only ate half of it, which I'm guessing was about a cup. What would you guess the calories were?
