Typical Japanese bakery chain located all over Tokyo, but this particular chain has more of the things I like than most other bakery chains. The quiche is fabulous, the chocolate chip muffins are heavenly, and the fruit smoothies are almost as good as a smoothie from Baskin & Robbins. They make fresh stuff all day long, but just be wary of the pre-made sandwiches...that thing you think is mayo probably has a healthy dose of horseradish.
This bakery is conveniently located on the basement floor of Akasaka Sacas. You can't miss it when you take the main elevators down. It's a little on the pricey side, but they serve very good apple cheese "angel soft's" as well as croissants! If you happen to be in the area, I'd definitely recommend some take-out before heading home.
They also serve a variety of drinks and have a seating area, but I would rather have a "sit-down" meal in one of the many restaurants in the mall or the surrounding area.
