It won’t surprise you to learn that seafood plays a big part in the local cuisine, and the restaurants that line the Promenade des Anglais offer up some of the freshest catches on a daily basis. Salade Nicoise (a tuna salad) is a local speciality, along with Pan Bagnat (a tuna sandwich).
Prices in Nice aren’t always friendly on the budget-conscious, and that’s not just restricted to those places in prime seafront locations, but there’s usually a set menu of the day, which means that 2 course meals at lunch and a glass of wine/beer shouldn’t set you back more than €10-15.
Apparently Fennochio’s in Place Rosetti has world-famous ice-cream, so a trip here on a sunny day would seem like a must.
In terms of watering holes, there are a few familiar locations - Ma Nolan’s offers a taste of home (next to the Opera house) with domestic and imported beers, and reasonable pub grub. McMahon’s, next to the Vieux Nice tramstop is another of the city’s expat haunts.
The Nice Tourist Office website has a comprehensive list of all the bars, pubs and restaurants in the city, with brief descriptions and key info such as opening hours. http://en.nicetourisme.com/what-to-do
