All Jolson is Ankh-Morpork's finest chef and its keenest eater - a combination made in mashed potato heaven. He got his nickname from the fact that no-one, seeing him for the first time, could believe it was All Jolson. He's the only man who shows up on an atlas and can affect the movements of small planets. He runs his restaurant on Broad Way.
He appears to be a good friend of Fred Colon (probably due to his prolific skills in the kitchen) and his ice cream in particular helped him out of a spot of trouble with over-zealous cart-clamping.
Comedy echo of Roundworld's Al Jolson, the US vaudeville performer who was voted the finest entertainer in the world in 1948, famous for his use of black make-up.
