Definitely worth going for fish and chips and then an ice cream. That is my plan!

There are other very good chippers and ice cream shops available (we are very lucky in Stoney on that front) but the Bay and AB are handily next to each other.
If you do get ice cream in AB, ask for all the toppings, you will be amazed, and if you have just walked all the way across Scotland you can forget about the calories.

Used to take the kids to the outdoor pool and then get an ice cream. They enjoyed the ice cream more than the pool as they didn't like the salt water!
