• Greggs, a British bakery chain, has more locations than Subway and McDonald's.
• It's best known for its cheap sausage rolls — as well as their vegan counterparts famously slated by Piers Morgan.

Greggs is something of a British institution.

The bakery chain has close to 2,500 stores in the UK. That's more than the 1,436 restaurants McDonald's had at the end of 2023, and Subway's roughly 2,200 stores.

Greggs is based in Newcastle in the northeast of England – and in some parts of northern England, it's hard to avoid.

The company just posted booming sales, with revenues up nearly 20% in 2023.
