The economist and food critic Tyler Cowen often writes that the best food is typically in low-rent areas for precisely this reason. If fixed costs are low, then the restaurant can afford to focus on the quality of the food a bit more. This is particularly true for many varieties of ethnic food, where the restauranteurs may be immigrants without a lot of money to put up, but a rich knowledge of the food from their home country.
