This is quite an unusual challenge with there being two ways to win. Either you have to beat the record number of patties consumed in one burger tower within 30 minutes OR you have to equal the current record number of patties eaten in a quicker time. A new record to beat is set by Beard Meats Food (go figure) when set a new record of 20 beef patties in 15 minutes. Although the record was beaten the restaurant has decided to keep the current challenge at 15 patties (the previous record) so regular people can still have a relative chance of beating the record. 15 Patties cost £25 - each additional patty and cheese slice with cost an additional £2. So basically, depending on what the current record will dictate how much you pay.
