While walking through Robson Square today and having Apple Stores on the brain, I remembered visiting the Milan Apple Store. Like UBC, it sits below grade and you can enter though a glass cube or down some exterior steps. I then also remembered seeing a proposal for a new UBC entry where the stainless steel UBC sign now sits, but I can't remember where I saw it, or what ever became of it?
