Bulb Coffee Roasters Roppongi is a two-floor coffee shop between Roppongi and Azabudai that serves drip coffee, lattes, waffles and sandwiches. Its signature items are the Valencia hot latte, which carries an orange peel aroma, and waffles, and customers can taste drip coffee samples at the counter before choosing beans. The space has full-length windows and is quiet between 7am and 8:30am, after which it gets crowded. Buying beans comes with a coupon for one cup of coffee.
