I just spent 5 days in Nice. Merenda is my hosts (who live in Nice 1/4 of the year) all time favorite restaurant in Nice. Please be aware you MUST make reservations here, they have no phone -- so you must go there during they day. They are also NOT open on weekends. Also, when you make the reservations you should see what's on the menu and if there is something you really want (like their lemon tart that is to die for), you should ask if you can reserve a portion for when you come in. Else, you may find that the food you see when you make reservations is not available when you go there. Also, beware the seats are some of the most uncomfortable you will ever sit on. The food is wonderful... I recommend their sardines, pesto pasta and lemon tart... but who knows if those will be available when you go in April.
