The king of cost-effectiveness in Hong Kong must be a café. Hong Kong locals also love to go to cafés to eat. The important thing is that the food they produce is delicious and not expensive, and the ingredients are full. Just order a set meal tastes very good. When it is cold, it will produce a small hot pot, clean and cost-effective. The most classic is a brother's pork rice and milk tea. The roast taste is also good. You can turn noodles to noodles. There are always several packages including a small soup and black tea at noon and evening. Some will also include an extra bowl of rice. You can share such a package with two people and eat very satisfied. When you are tired from shopping, you can go in when you see everyone, it is definitely affordable.
