The pop up cafe has turned a joke by satirical website Ulster Fry into reality and begins trading as Simply Crispy, boasting 35 different varieties of flavour.
Andrew McMenamin, who owns That Wee Cafe in Bedford Street, offered to transform his business when he read the spoof online.
He said: “Hopefully it will rekindle a few childhood memories. It is a bit of fun, it is not to be taken too seriously.”
Customers will be able to choose their bread, crisps and add cheese or ham to their sandwich, which will be served with soup and chips.
Tayto, a Northern Ireland-based crisp manufacturer which is one of the largest distributors in the UK, will provide most of the crisps “due to its large variety” but Walkers will also be represented.
Among the bread on offer will be the traditional white Belfast bap, a large crusty round bread which can be split in the middle and stuffed with fillings.
Mr McMenamin added: “We are riding on the back of the publicity the cereal cafe got in London, if it helps us and Ulster Fry then it is a good thing.”
The Cereal Killer Cafe opened in Brick Lane, London, last year and sells classics like Rice Krispies. It was established by Belfast twins Alan and Gary Keery.
Mr McMenamin would not be drawn on the long term prospects for his own novel venture.
“It is certainly play it by ear, hopefully it will rekindle childhood memories of Belfast baps.”
The idea has been credited to comedy writer Seamus O’Shea and his writing partner Billy McWilliams, who run the Ulster Fry website.
