John Travolta once famously asked to sample the $5 shake in Pulp Fiction, but that is small change compared to the princely price of one ale at a South Wimbledon pub.

Drinkers at the Trafalgar in High Path can now shell out £100 for a pint of Gale's Horndean Special Bitter (HSB).

The Trafalgar is pulling pints from its last ever barrel of the Horndean-brewed beer, as the Hampshire brewery has now be taken over by Fuller's of Chiswick. Gale's beers are now being produced in London.

Demand for the special pint has been so high that landlord David Norman is challenging drinkers to pay the three-figure sum for the privilege of enjoying one final Horndean tipple.

Mr Norman said: "We want to highlight the end of an era. We've stocked the beer in the pub for 20 years and it's a favourite for a lot of people."

One customer has already splashed the cash on a pint.

Keith Chapman said: "It's the best beer in the world and it's the last barrel of it. I've got to drink it while it's still there."

Regulars need not be bitter, however. They can still purchase the beer at its usual price of £2.50 if they buy a voucher.

But Mr Norman added: "Anyone who comes in to buy a £100 pint will be glad to know they'll be helping the Stroke Association our chosen charity this year to the tune of £97.50."

The Trafalgar dates from the 1860s and is the oldest free house in Merton.

But while the pub may have a long future ahead, fans of HSB should get down there soon before the final barrel runs dry.
