Here is a list of Cafés that I have visited so far in Lucerne, each and every place has its own flavour and atmosphere, some are also restaurants while other even offer co-working spaces, include a shop or can be perfectly combined with a visit of a Museum or the Cinema next by (in alphabetical order):
Alpineum : https://www.facebook.com/alpineum/
Next to the Löwendenkmal. A small but cosy place. Can be crowded in peak times (lunch time, afternoon tea time, apero time) but
Bistro-Bar Bourbaki : http://www.kinoluzern.ch/bar-bistro/info.html
A drink or coffee can be perfectly combined with a movie at Bourbaki Cinema or the Museum in the same building (http://www.bourbakipanorama.ch)
Café de Ville – Schwanen : http://www.cafedeville.ch
Noble and traditional Café, lots of magazines, terrazza was in renovation when I went there, beautiful views (also soon again from the terrazza).
Café in the Museum of Arts : https://www.kunstmuseumluzern.ch/cafe/
This Café is located on the 4th floor of the famous KKL building next to Lucerne’s main Station. Can be perfectly combined with a visit to the Museum of Arts. Offers a nice ambiente and beautiful views to over the bay and lake.
Café Lokal : http://www.cafe-bar-lokal.ch/
A tiny place but apparently well known and frequented by locals, that’s probably somehow the hint for its Name. Next to Museum of history and nature. Reuss-river view.
Café Sowieso : http://www.cafesowieso.ch/home
Social Enterprise with arts Exhibition in the Café/Restaurant. Local seasonal cuisine.
Chez Cassis : www.chezcassis.ch
A colourful and cosy place. Combines coffee and a shop and they also organize concerts.
A number of traditional (“tea-room style”) Cafés invite for a coffee/tea with a nice Piece of cake or salty dish.
Mardi Gras : https://www.facebook.com/pages/Mardi-Gras
Friendly Service, nice and arty place. Cakes, magazines. Attracts a mix of People.
Mill’Feuille : http://www.millfeuille.ch/
Offers a beautiful view onto the Mühleplatz and river Reuss. It is also a Restaurant. Nice atmosphere.
Neubad Bistro : http://neubad.org/Bistro
It used to be a bath that has been transformed into a creative and collaborative space. It has a nice coffee/restaurant place, work spaces, Shops inside and different Events are organized.
I like the atmosphere, most beautiful and irrestistible deserts. Offers also finger Food and international wok dishes.
