Stopping in here is a great idea. The mini road network is a great way to teach childern basic road safety. Just remember to stop and look both ways before crossing the "road".
However, a word of warning. During the summer months is place can be quite busy in the weekends. So do try to avoid peak times during the weekend so as not to alert the muggles.
Have fun searching!
