Anyone who rocks up in their bedwear and posts a photo of the occasion on Instagram will get a free brekkie.
All you have to do is make sure you include the tags #PJsAtFrankies and @frankienbennys in your post.
According to The Sun, the offer will run between 12 and 17 October, and you won't need a voucher or code to
The outlet reports that participating branches include Spalding, Peterborough, Romford and Inverness, but not all of Frankie and Benny's 95 restaurants are getting involved, so you're best off checking before you head out in your PJs.
The free breakfast offer - which has been launched to promote the chain's new menu items - will be available from opening until midday.
The perk is that you'll simply be able to roll out of bed and down to your local Frankie and Benny's, wearing your favourite dressing gown and slippers.
The only thing to bear in mind is that you'll be at a family restaurant so 'attire choices need to be PG'... Perhaps leave that silk nightie for the bedroom, and if you're used to sleeping in just your boxing shorts, maybe consider grabbing a robe before you leave the house.
Once there, you'll be able to try out any of the six new dishes on the breakfast menu, including brioche bread French toast, mushroom and cherry tomato hash, and a beef brisket hash.
There will also be a brand new option for children with the kids' yoghurt and fruit sundae.
Other offers listed on Frankie and Benny's website also include 20 percent off food for NHS staff, 20 percent off food for students and 30 percent off food with a cinema ticket.
The chain is also offering students the chance to win their tuition fee, saying: "All you have to do is share a picture of yourself enjoying a meal at Frankie & Benny's or tucking into a takeaway, including any Coca-Cola product (Coca-Cola, Diet Coke, Coca-Cola Zero Sugar, Sprite, Fanta or Appletiser). Post it on Instagram with #StudentsWinWithFrankies and @frankienbennys and let us know in the caption where you study and why you believe they should win. It's as simple as that!"Featured Image Credit: Frankie and Benny's
