This hot pot is actually called "salty fish with chicken cubes and tofu hot pot", and came in a set including a bowl of plain rice and a drink. It costed me HK$48, but I thought the shop owner got a net profit of HK$45. Salty fish isn't expensive at all, but I couldn't find more than 1 gram in it. And there was less than 5 grams of chicken. 80% of the whole thing was ginger, garlic and onion. Though it was very hot and kept me warm, but the whole thing was actually tasteless.
