Brad and Amy took me to Japango for sushi last night and it was excellent. It seemed fresh, the waitress was friendly and accommodating, and it was quiet enough to have a conversation. It also emitted a certain "hipness" which I should have expected, given my hosts. Hence, being an 18 year old very focused on where I'm seen, Japango probably improved my image in Boulder considerably.
Overall, good sushi and service, highly recommended.
