I think that Arab/Lebanese/Palestinian food from that region in the Middle East is excellent and very diverse. I also believe that this is a food culture that has a very limited crossover to restaurant culture. Most local restaurants represent a very narrow range of local cuisine (mezze + grilled meats) - and it doesn't matter if the place caters to mainly local customers or tourists.
Automatically, I associate France with having a very dynamic restaurant culture in representing French cuisine - but I'm curious, what are other cuisines that are either very well represented or not in local restaurants. No need to make this a thread about talking about how a cuisine is misrepresented in restaurants abroad - but basically is it a cuisine is most diverse in home cooking or if it has a well cultivated restaurant tradition.
