I'm Elizabeth Hotson and in today's Business Daily, necessity is the mother of invention.

I'll be finding out how restaurants and other food outlets,

some of the most obvious casualties of the pandemic, have adapted to survive.

In the way that only a pandemic allows you, we just reached out to everyone and said,

we're trying to fight for survival here.

We're going to put these kits up.

We can't tell you when you're going to get it.

You will get it at some point in the next six weeks.

You know, I guess that's, you know, out of adversity comes the best stuff, right?

And in London's Knightsbridge, a world-famous name is trying to maintain a stiff upper lip. I mean, there is nothing efficient about this.

We've had to rewrite the rules. All of those things that you took for granted have all gone.

And I have to say none of them are nice. This is Business Daily from the BBC.

It's late December and here in London and the rest of the UK, we've been in and out of various coronavirus lockdowns and restrictions since March.

I'm standing a few minutes away from the BBC office.

It's nearly lunchtime and despite the constant drizzle and threat of a downpour,

in more normal times I'd be fighting for pavements base with hungry office workers. But we're not living in normal times and I've pretty much got the street myself. On this road alone,

three purveyors of variously bagels, sushi and sandwiches have closed permanently, and the ones that

have stayed open, at least when they're allowed to, have had to adapt. In yesterday's episode of Business

Daily, we saw how workers' eating habits have changed over 2020, and today we'll be looking at the

other side of the coin, or service hatch, namely the outlets supplying much of that food.

And where those outlets are concerned, London isn't alone in its struggle.

It's been a similar story in other culinary hotspots.
