Although Paris is the capital of France, the cost of living is high, but the food and beverage price is not high. In other Chinese restaurants with 21 euros, the same quality can be won in Paris 14 euros. So if you want to have a full stomach, the easiest way is to have breakfast café+bread =3 euros+two Chinese food buffets at 16 noon and 18=37 euros at night. If you eat French food, this price is just the price of a meal, which is probably not enough. If you live in a supermarket for a long time, half the price is enough.
