Harrods is selling one of the most expensive takeaway sandwiches in London for £28, complete with Wagyu beef, truffle and gold mayo

Harrods is selling a takeaway beef sandwich for £28, making it one of the most expensive sarnies in Britain.

The Wagyu Steak sandwich features Wagyu beef, most likely imported from Japan, with porcini mushrooms, golden mustard mayonnaise, mushrooms, arugula, stewed onions and truffle butter.

Truffle, one of the most expensive ingredients in the world, typically costs between 65p and £1 per gram – which perhaps explains the sandwich’s high price tag.

By comparison, a roast beef and horseradish mayonnaise from M&S costs £4, meaning customers can buy seven for the same amount as Harrods’ offering.

The Wagyu Steak is available for purchase in the food hall of the Harrods flagship store in Knightsbridge, West London.

Food buyers can also purchase Wagyu Katso ‘Sandos’ (Japanese for sandwich) for the same price.

These sarnies are filled with fried Wagyu ribeye measuring approximately four by four inches, together with mushroom ketchup, barbecue sauce and white cabbage.

It comes after Pret a Manger found itself in the line of fire for selling a £7.15 baguette.

The Posh Cheddar and Pickle Baguette contains mature cheddar, chunky pickle, roasted tomatoes, sliced ​​red onion, free-range mayo and mustard cherry, wrapped in stone-baked bread.

Customers reacted with dismay on social media when the eye-watering ‘dine in’ price for the chain’s ‘posh’ sandwich was marked down at a London Tube station branch.

The baguette costs £5.95 at transport hubs to take away – and, when combined with a £1.75 bag of crisps and a £5 green smoothie for a full lunch, it costs £12.70.

To eat it in store, the chain then charges £1.20 VAT on the sandwich, bringing the price to £7.15 and the total deal to £13.90.

The price of the sub drops by more than 20 per cent to £5.72, including VAT, for those who have signed up for the £30 per month Club Pret membership and want to eat there.

Sophie Gallagher was ‘completely tipped over the edge’ by the price tag and argued she was not in an airport or major travel hub.

Her tweet went viral on X, formerly Twitter, with more than 1.4 million views and 320 comments.

She wrote: ‘What the fuck is happening here.’ Before I add, “I want it to have an estate for that money.”

Many joked about the ‘posh’ nameplate, while others simply said she should have gone to Greggs instead.

A spokesperson for Pret said: ‘Prices of our products are typically higher at train stations or transport hubs, due to higher operational costs, and as with all food-to-go retailers, dinner prices are subject to 20 percent VAT, just like the case with the price listed here for our Posh Cheddar Baguette.

‘The vast majority (87 percent) of our sales in the UK are takeaways, so most customers are not subject to the additional 20 percent VAT.

‘Like all companies, we are faced with enormous cost pressure, which we try to absorb as much as possible. We continue to offer great value for high quality, freshly prepared food and organic coffee, in addition to a specialty sandwich range, Made Simple.

‘We have also recently doubled the Club Pret discount to help customers save even more. So subscribers can now get 20 per cent off everything in store and up to five barista-made drinks a day for £30 a month.”
