Not sure about Westworld, or whatever that place on Douglas where Victoria Fitness Exchange used to be is called.
My wife and I had our MacBooks repaired at Westworld, really happy with the customer service and quality of their work. We did not buy our MacBooks from there, and they were at the end of their Applecare when they did the work...but basically we would be happy to buy from them in the future as it was a good experience.
