A review is being carried out into the growing trend of pop-up bars appearing at major events in Hull city centre. It follows concerns over their impact on business at established pubs and bars during festivals.
A report due to be discussed by councillors this week says this year's Freedom Festival attracted a high number of temporary event notices granted to premises that do not normally operate as licensed premises.
The report adds: "These extra temporary event notices doubled the amount of licensed premises on the Marina area and had a detrimental impact on the traders who operate throughout the year."
An informal events safety advisory group made up of representatives from the city council and the emergency services is now examining the issue of pop-up bars appearing at events across the city centre.
The report says the group is also reviewing the annual Yum food festival after this year's event included a large temporary bar.
Feedback from partners suggested the event "featured too much alcohol-related activity".
