Well, I cannot answer the poll because the answer is "It depends..."
If I am in Chinese restaurant I will go with either unidentified oolong or Dragonwell, and trust that the proprietor knows his teas, which they usually do. I don't remember a bad tea in Chinese restaurant.
If I am out for sushi, and they have some matcha blend on the menu, I will have that and will terrorize them about the exact name and prefecture it came from.
Otherwise I'd have Darjeeling, because I am weary of what they call Assam in general restaurants that are not tea houses.
Today I was drinking Assam Boisahabi estate all morning. And now am enjoying the first infusion of Victoria's Own Blend
. It smells awesome and is very tasty as well as interesting. I can't wait to make a second infusion because, as I understand, that's when the oolong part will become evident. Excellent tea, Victoria! Thank you for sharing it.
