How should I kill time waiting for my hotel check in

My bus will arrive at 6 in the morning at sec 43. And my hotel check in starts at 12 PM. What do you think I can do to pass time? I don't wanna just stand there. Any cafe that is open that early in the morning? Is there any place that I can visit? Ofcourse, add any safety tips as this is my first visit to chandigarh. I'm here for 2 days. All suggestions are welcomed.
