I really don’t understand your way of thinking? Why look for machlokes? Should we then all be eating only American food? After all we live in America!!!! How dare we open up Heimisch European Restaurants and Take out? Are you saying there are or were no Jews in China, Mexico, Italy and the like?
Here is a history lesson for you. Jews live all over the world, and there is no reason why Yiddin should not taste the foods from other regions. We don’t need to be narrow minded. In addition there is no reason for people not to make parnasah opening restaurants, it is a means of feeding one’s own family as well. If you choose not to eat out then don’t but don’t judge others. There are way too many double income families who need the help and break just to keep things on an even keel. And that is not called fressing that is called living.
