There are many reasons to go to the Brasserie des Halles de l’Ile: its central location, its incredible view over the Rhône River, its industrial architecture, the table in an old cable car, or the fact that it is big enough so you can almost always find a seat in this huge café-restaurant.
The best reason for me to go there is its Sunday brunch (CHF 49 with drinks). The buffet is impressive. If you like sweet tastes you have a choice between croissants, cakes, pancakes, tartines, mousses, etc. If you prefer savory food, the buffet offers a variety of cold and hot dishes. I found that there is surprisingly little cheese, but who cares when a traditional cheese Raclette is offered around 14:00!?! It is highly recommended to make a reservation for the brunch.
The tapas and wines at the Brasserie makes it famous for after work parties. Music and dance also liven up the evening and on Sunday afternoon, Salsa classes and parties are organized several times a week and DJs are regularly invited.
