Haidilao's requirement to order the bottom of the pot is not a disguised price increase, because the bottom of the pot is the basis of hot pot, and if you don't order the bottom of the pot, you can't enjoy the hot pot service, which is the basic rule of hot pot restaurants. When Haidilao introduced this regulation, it also made it clear that this is to ensure the quality of dishes and the standard of service, not to raise prices in disguise.

However, some consumers may think this is a bit unreasonable, because in other hot pot restaurants, the bottom of the pot is usually optional, and the price is extra. Therefore, if consumers have different opinions on this regulation of Haidilao, they can choose to eat in other hot pot restaurants.

In short, Haidilao's requirement to order the bottom of the pot is not a disguised price increase, but it may be unfair to some consumers. When consumers choose hot pot restaurants, they should make choices according to their own needs and preferences.
