Papa's Fish and Chips on Foreshore Road, alongside two of the chain's other stores in Hull and Cleethorpes, will be selling regular fish and chips for £1 and hope to raise £10,000 for the charity.
A spokesman for the chain said: "We love working with our local communities to help make a difference – so in doing this we’re hoping to raise over £10,000 for this great cause."
There will be additional fundraising activities and entertainments in the restaurant to try and raise as much money as possible.
Activities across the three restaurants include a Batter Bucket Challenge, Batter Baths, bouncy castles and more.
The offer will be available from 11.30am onwards.
