The main difference between AYCE and à la carte is the price. AYCE hot pot restaurants will charge you a fixed price, usually per person, which allows you to order as much food as you want. à la carte hot pot restaurants, on the other hand, will charge you for each dish that you order.  Another difference between the two is the variety of food that is available. AYCE restaurants usually have a much wider selection of ingredients and dishes than à la carte restaurants. This is because they need to cater to a large number of people with different tastes.  So, if you are looking for a cheaper option with more food choices, then AYCE is the way to go. If you are looking for a more intimate dining experience with fewer people, then à la carte might be a better option for you.
