With Champagne bubble bath bars and selfie cafés on the horizon, London’s appetite for the silly appears insatiable.

But don’t knock it. While at times London’s pop-up scene serves up ample Get in the Sea fodder, at others it offers us gems such as this – a roast potato pop-up.

And it’s not just any old roast potato pop-up either, this is a roast potato pop-up that has a gravy fountain – which is just like a chocolate fountain but flows with gravy for you to dip your spuds in.

There is a catch in that the pop-up – named Sunday Best – is being hosted by frozen potato company McCain, best known for their oven chips.

But the company is working with ingenious foodie creatives The Robin Collective to bring it all together and there’s plenty to be intrigued about.

Dishes to try will include roast potato kebabs along with roast dinner ice-cream 'Sundays'. The verdict’s out on those, but the gravy fountain is a sure fire winner.

Sunday Best is open to the public on October 23 at 18 Maddox Street, W1S 1PL. Tickets are avaialble now.
