If you go to one of the big cities in China, you will find lots of restaurants in the street, so there is no need for you to worry about food, but you do need to think about what sorts of style you are looking for. By learning "Where is the closest restaurant?", it takes you less time to find a restaurant and have more time to enjoy your meal. It is also a good question to ask when you want to catch up with friends for lunch or dinner. So enjoy the video and master the sentence :)
