Tokyo, Japan｜Yakiniku YORONIKU TOKYO AZABUDAI HILLS

In the past, buying car and ferry tickets through KKday was convenient, fast and affordable, so this time I booked Tokyo Yoroniku Truffle Meal through it for HKD1,029 per person, HKD3,087 for 3 people. After arriving at the restaurant and looking at the menu, it only charges Yen13,400 per person, which is only HKD724 per person at current exchange rate of 0.054. Booking through KKday even pays HKD305 more per person (42% of the meal price). You charge HKD100-200 is fine, but charging 900 to book a restaurant, is it excessive? I will never use it again.
