As a rule of thumb, the further south you go in Europe the better the quality of food gets. Especially the basics, like vegetables and meat or fish. That being said, us Germans are bread fanatics. We do suck when it comes to overall food quality. We'd rather pay 100 bucks for a frying pan to cook to cheapest discoubter meat instead of payibg 10 bucks for the pan and investing the other 90 in high quality meat from the local butcher.

That is also how California style cuisine is described.

Easy to say when nice advocados are a dime a dozen. The US has so much better fresh edibles than say Ireland.

"California style cuisine" focuses on local ingredients, if you had a "California style" restaurant in Ireland it should focus on things like beef, grains, cabbage, carrots, etc. but it would be prepared differently.
