The luxury hotel that became a burger joint

The Waldorf Astoria is a luxury hotel and spa in Amsterdam where rooms start from $700 a night.

It has a two-star Michelin restaurant, a prestige canal-side location and is set in six 17th- and 18th-century palaces.

To keep some staff busy during Covid-19, the Waldorf Astoria Amsterdam hit on the idea of offering deluxe burgers for delivery, Reuters reported.

The chefs had to come up with something unique, said the hotel's manager Roberto Payer.

"The way we do it, the way we prepare it, the way we serve it, the way it comes home is very different to any other burger," he said.

For 19.50 euros ($23) plus an Uber Eats delivery fee, the Waldorf Signature burger comes with a 240-gram Holstein-Fresian meat patty and is served with English Duke of Berkshire bacon on a French brioche bun with aged Dutch cheese and homemade relish.

Uber Eats reviewers have awarded it 4.8 stars out of 5.

Crafting the perfect burger took serious research, said executive chef Sidney Schutte, who during normal times runs the two-Michelin-star Spectrum restaurant, which does not serve burgers.

"It had to be 'the best burger that you can buy here in Amsterdam'.... it needs to be perfect," he said.

Dutch plans to ease some Covid-19 measures have been pushed back until April 28 at the earliest, so the burger remains on sale for now.
