This is an excellent restaurant in Grenoble. My fondue experience is limited, but their fondue is…read morevery tasty. I went with three other people and we had the Forest Fondue and Imperial Fondue, and a chocolate-walnut fondue for dessert. The portions are very generous, and there was more than enough fondue to go around.
Additionally, the service is very good and friendly to foreigners. It was also open around 8pm on a Monday night, and it can be difficult to find sit-down restaurants otherwise. They also served a shot of their Green Chartreuse on the house after the meal, which was pretty tasty.
