It's on the ３rd floor of Keio University. With its calm atmosphere, it's perfect for afternoon tea^_^

A luxurious lounge operated by Palace Hotel, with an atmosphere like a hotel lounge. It's in a somewhat hard-to-find location, and you can only enter if your group includes a faculty member or alumnus, so it feels like a hideaway, which I really like. The menu selection is fairly small. Sometimes professors and seminar students are chatting happily, but generally you can enjoy coffee quietly, so it's a favorite of mine.

It has the luxurious feel of a hotel lounge and is relaxing.
