Restaurants whose clientele is mainly foreigners will often adapt their menus to what they think foreigners want, and their prices to what they think foreigners will pay. So, if you want to eat the local food as ordinary locals will eat it, and you don't want to be ripped off, then you might want to avoid places where the other diners are likely to be fellow foreign tourists.
