Geneva restaurant in Paquis for Sunday lunch.

Hi!
I will be in Geneva on Sunday 4th of April because my husband will run the marathon.
After the run we want to have a nice lunch. If the day is sunny I imagine a restaurant with an open air area, something on the lake shore or similar. If the weather will be bad obviously we'll take in consideration even "closed" restaurants.
Do you have something to suggest (not too expensive!)?
Better if in the Paquis area, because our airbnb flat is there (Rue Philippe-Plantamour).
Thanks! :-)
