THE Bavarian restaurant is turning up the heat for National Chicken Wing Day on Sunday, with a line-up of spicy challenges, red-hot prizes and 10-cent wings all day long.

In celebration of all things chicken wings The Bavarian will host a fiery ghost pepper challenge.

Ghost pepper wings are smothered in a special haus-made sauce made up of three different kinds of pepper - cayenne, habanero and the hottest of them all, ghost pepper.

Competing for a $200 restaurant voucher, contestants will eat one dangerously hot ghost pepper wing a minute, with the last person left standing crowned the champion.

The challenge costs $20 to enter and kicks off at 3pm.

Spectators can feast on chicken wings for just 10 cents each, while guests keen to taste a ghost pepper wing can try their hand at Wing Roulette for $20 which includes a basket of five saucy diablo wings with a surprise ghost pepper in the mix.

Diners can cool off with some brews on tap including imported favourites Löwenbräu, Franziskaner, Stiegl and Hofbräu, as well as a large range of craft beers.
