We stayed 4 days. In lunch time, we went to the restaurant for eating lunch buffet. First time, female staff said " you should not wear the short pants for entrance". So we went back my room to change my pants. Second try, same female staff also prevented our entrance. She said "your daughter cannot enter the restaurant because she looks like under 7 years old". So we said "why you don't say on previous time?". We upset for this woman staff. You can inform this rule in check-in. I will never use this restaurant in my life.
