A good location for getting Phillips appliances is the 17th Floor of Hopewell Center in Wanchai. They frequently have good deals on floor displays there.
The "gas lamp street" is Duddell Street, but I have a feeling that Philips showroom may have recently turned into a Siemens one - there's certainly on of those on the junction of Duddell & Ice House Street.
You are too kind. It is more likely I don't know my Philips from my Siemens and I am too far away from my wife to get the actual answer.
