Not really. Most restaurants don’t care, as long as I don’t take picture of their operations (kitchen, cooks, et al). So far, only one restaurant have not let me take pictures; however, I was told it was because of the decoration (it has some items of “historical” significance). I don’t buy it but… Other than that, so far, there has been one instance where another guest wondered (aloud, I might say) if I am from the media. ^_^;
