René J: Restroom codes are changed rather frequently. Ask the staff for the current ones and don't expect the ones given in Foursquare to be correct. :)
Jose Klee: my relax lounge when the other guests are rare ;) pitty they removed their ice tea assortment. i'm going mostly for the venti capucino and their frappucinos blended cream =)
Elisa Bieg: The largest Starbucks in the center. Great for informal meetings and book clubs and such, as long as you site downstairs. Best mid-morning, weekdays - less people, that is.
Noonamsom Narumon: If you want to enjoy the view of the famous wooden bridge of luzern with the comfortable couch and some nice drink, this place would be one of the best choice:)
