Hope it's okay to pimp his book on this site.
I have to say, his book titled "Provence and the French Riviera" was excellent. I've just returned from 8 days in Nice and I took the book with me everywhere I went. If you want to get the most out of your vacation, just do exactly what he says, eat where he recommends, and skip what he says to skip (such as Cannes, unless you just can't live without seeing where they do the film festival...)
It's so detailed too. Right down to where you should sit on the bus to get the best views, where to get off, which line to take, etc. In a region filled with thousands of restaurants, it's often very difficult to decide where to eat. You only have so many chances to enjoy a meal, and it sucks when you feel like you wasted one on a bad place. Fear not! Just eat where Rick says to eat. Every place he suggested was absolutely perfect. He even lists the owner and/or managers names in the book. I lost count of how many times I joked with my wife that "Rick was right!" Or, "We really should have listened to Rick!" LOL.
