A branch of popular Liverpool takeaway The Lobster Pot wants to serve alcohol until midnight under newly submitted plans.
The Whitechapel restaurant, one of two in the city, has also appealed to councillors to let it stay open until 5am on Friday and Saturday to serve customers coming from Liverpool's pubs and clubs.
It currently opens until 3am on Friday and Saturday and can sell alcohol to customers eating inside the restaurant until 7pm.
If its plans were to get the green light it would still only be able to sell alcohol to people planning to eat inside the restaurant as opposed to people taking food away.
But the new plans face stiff opposition from both the police and council who say the later opening hours breach a policy put in place to limit negative effects caused by late night premises.
The Whitechapel branch of The Lobster Pot is located in the Cavern Quarter Cumulative Impact Policy (CIP), which covers a zone of the city where there is a high concentration of pubs, clubs and late night takeaways.
The CIP is designed to limit the effects of these premises by giving councillors more power to refuse new applications in areas where there are already a large number of premises.
In a submission to members of Liverpool Council's licensing sub-committee Andrew Blackmore, from the city's licensing authority, says: "The premises do not fall within any of the exemption criteria for the Cavern Quarter CIP and any increase in hours would add to the existing cumulative impact in the area."
Merseyside Police's statement to councillors echoes Mr Blackmore's.
Councillors will decide on the application at a licensing meeting next Wednesday morning.
