Cleanliness outside restaurants

As they claim to provide the most hygienic and clean food, what about the place to actually give the first impression?
I imply the place just outside these so called "highly hygienic" restaurants. They may put their heart and soul in the cleanliness of the food and dishes they prepare, but what about the cleanliness of the environment and surroundings in which they have set up their "highly hygienic" restaurants? They may have won awards and accolades for being the "highly hygienic" and good food giving restaurants, but what about the question of the place outside being clean or not? No wonder why people often eating from outside fall sick so easily and so often!
