With the exception of serve your self style of service restaurants basically copy each other on the overall operating format of how the customers are served and taken care of right down to including "similar" items being listed on the menus. They all keep a watchful eye on each other to see what is working well and may change a menu method of service cost or whatever the case may be to accommodate current customers and coax new paying customers to spend money in their establishments. It is a constant see saw battle. Regardless of these restaurants copying and competing with each other for our dollars they clearly are the bar to which we compare the taste of our favorite foods to.
Some may even look to make improvements on the original. It can be for other reasons like notoriety or personal challenge for pride and maybe even some kicks. Think about this comedians can get more laughs if they are good at imitating some one else right? If they are really good at it this helps bring more people to their show. Just as is done with so many other things that are made there is always a group of these interested individuals that like to do things themselves. These people will go out of their way to copy favorite recipes from all of these restaurants. I would venture to say that if one were to interview many of these DIY (Do It Yourself) people it would be primarily in an effort to be able to save money as a main reason initially.
Many sites are recommending the same key original sources (recipe hackers) of the imitation or copycats recipes and in my experience this is usually a good hint as a reasonable place to start. Why? There is always someone who highlights their experience and discovery of things that have had impact on their life with how and why they did it. Many times they get even further into it and begin marketing their efforts to generate some additional income. It may be the result of a friend or family member that cheers them on but if it is done well and the quality is there it often times catches enough attention to make it worth the while.
