Sounds good - see you at the piano.
Raveninhk - this lunch is in Wanchai not Central. The piano in question is in the Central Plaza lobby (Central Plaza is on Harbour Rd Wanchai opposite the Convention and Exhibition centre). It's an easy meeting spot if you work in the building, but not that close to the restaturant. So if you are not coming from Central Plaza, may be easier to meet at the restaurant.
Hope that hasn't totally confused you...
