Manor is the best grocery in the city. Great fishmonger with fresh seafood, also good meat and cheese and bread. And it's a department store — so if you need a pair of shoes, a gift, a watch, a kitchen knife, or something for the house, you're already there. Efficient Geneva errand running.
The fishmonger gets fera from Lake Geneva. Lot's of local produce here, wine, cheese, veggies, etc.
