Are you crisp in or crisp out?
That is the question being asked by a popular city sandwich shop chosen for Walkers' ultimate Crisp In sandwich menu.
Logans, in Swan Lane, is one of seven shops across the country to partner with the manufacturer.
Each outlet has created a unique sandwich centred around a specific crisp - with Logans' being a twist on the BLT with bacon, lettuce and Walkers Baked sea salt crisps.
This is on a white baguette with spicy cheese and a slaw made of grated carrot and red onion.
"We do specials a lot," said Logans owner Anthea McNamara.
"And so far it's been going really well.
"Obviously the BLC is ours, but it's been really nice to work with other places across the country.
"Having the backing of such a big brand like Walkers has also been amazing."
The Norwich shop is joined by sandwich shops in Glasgow, Newcastle, Liverpool, Reading, Brighton and London.
They have created products including the Ultimate BBQ Chicken, the Cheesy Reuben and the Chicken Tikka Wotsits.
"The ultimate BBC Chicken has been selling well," added Anthea."But we've noticed that this has allowed the team to be really creative and we've been trying so many different combinations.
"There are three days left now and we're hoping they'll be just as good.
"But I'm sure the debate with continue as to whether you are you crisp in or crisp out."
The full menu at Logans features the BLC, Mighty Monster Munch, Ultimate BBQ Chicken, Kickin Chicken, Cheese and Onion Slam, Chicken Tikka Wotsits and the Cheesey Reuben.
Our BLC review
So, is the Logans BLC any good? Evening News reporter William Warnes gives his verdict.
I was shocked to discover just how fierce the crisp-in and crisp-out debate truly is.
Comparable to the Norwich/Ipswich rivalry, it seems the controversy is enough to split families and even newsrooms.
The BLC from Logans was no different.
Filled with bacon, lettuce, spicy cheese and ready-salted Walkers crisps, the sandwich received a mixed reception at Evening News HQ.
Some seemed appalled at the idea and reacted in a way only comparable to being told they would have to spend a week at Portman Road.
While other, more open-minded individuals seemed to embrace it.
As a crisp-in man myself, I was all for it.
The Logans sandwich was full of flavour and the crunch - while slightly understated - provided a new take on the classic BLT.
It is always brave to put a new spin on such a timeless and well-loved product.
And this is especially true when that spin is as controversial as putting crisps in your sandwich.
But rivalries aside, I encourage everyone to head down to Logans and try this while you still can.
Only then will you truly know if you are crisp-in or crisp-out.
Is Norwich Crisp In or Crisp Out?
Sophie Brooks hit the streets to find out how city folk feel about crisps in their sandwiches.
"I love a crisp sandwich, said Jade Middleton, 35, from Norwich.
"Salt and vinegar or prawn cocktail.
"I grew up with those kinds of things, so absolutely yes."
32-year-old Vincent Nally, from Fakenham, echoed his love for crisp sandwiches, describing them as "the way forward".
But the debate is a fierce one - and not everyone is on board with some added crunch.
Kizzi Copping, 18, from Norwich, said she didn't like them as there are "way too many textures going on in one go".
Others described it as a "concerning combination", while another said: "That’s something my son would do, so absolutely not."
Hannah Lee, 48, from Stoke-Holy-Cross, added: "I’m not a fan but my husband will have them basically every day."
