Not sure if this is a tip, or wanting to hear other thoughts. We thoroughly enjoyed our time (spent 2 hours) at Starbucks Reserve in the Shibuya area. My god, the Knob Creek / Starbucks collaboration as a cold brew was mind blowing.
About a 10 minute walk from Naka-Meguro station, plan to go early. We were lucky that there was no line, but within the next hour, it started getting busier and busier.
