I have been here more than once, and my experiences were generally positive. However my last visit was completely disappointing, because one of the barista was unbelievably rude.
It was a cold Sunday morning, I entered the place and asked for green tea. The guy just cut me off in the middle of my sentence, telling me impatiently that "I don't have green tea."
I tried to point the teabags hanging out of the boxes behind him, he just kept on repeating the same thing.
Then he just ignores me and serves the next customer. Yeah, he turned his head towards the next person in line and said "How may I help you?" as if I wasn't there.
I am still confused to this day.
