Culture, sports and tourism minister Rosanna Law said operators of Kai Tak Sports Park made improvements every day during the three-day Rugby Sevens tournament.

Speaking to reporters on Sunday afternoon at Kai Tak, Law said the atmosphere and operations at the venue were very good in general.

"I also had to wait in line for some time when buying a hamburger yesterday, so I told the venue operators to enhance their food supply services. The operators increased their supplies today, and I know that more staff were arranged to help out at vendors at the arena and youth sports ground," she said.

Law added that more improvements can be made in terms of the variety of food available, and whether to boost taxi services there.

She also called on fans to make use of the MTR and buses to leave the venue when the Sevens draw to a close.
