QuangZhou Milk Oolong (no actual milk in it) is the best! I tried it with milk (latte) with a little honey - I think I still prefer the regular version.
This DavidsTea is convenient to many offices and is accessible via PATH.
Serivce was good to start with, but my drink seemed to have been forgotten while the people behind the counter were helping other customers. I waited for quite a while - definitely longer than the steeping time for my tea.
