Evan: Best spot to take birds eye view of the crossing would be Magnet 109 (on the observation deck, 300 yen entrance fee) and Starbucks (this location is generally always packed).
Evan: Cafe by day, cocktail bar by night, and vintage furniture boutique all year round. Great caffeine fix before exploring nearby attractions, like the Meiji Shrine. Quieter part of Shibuya (15min walk from the station).
Evan: This spot is the most popular for Onibus Coffee, which is inside a traditional Japanese house with a very #aesthetic al fresco area. Each store features a quaint, straightforward interior that matches the menu: espresso, americano, and hand drip - nothing more, nothing less.
Evan: This location has a smaller space, but that's okay! Grab a coffee and stroll around the park. Great music (owner, Daisuke Hamada used to be a DJ!). Menu consists of four seasonal single-organ drip coffee. Recommend the house blend, which comes in espresso, macchiato, and Gibraltar. They also have good latte with equally good foam art too.
