The law of supply and demand and the good ones build up a long-standing custom and thrive.
A lot of people think that they can get into the business as they "like" coffee or food and they end up closing after about only 6 months as they cannot manage all the overheads or even know their customer.
No point selling sushi rolls, quesadillas with chilli flakes and gazpacho soup when the majority of the locals just want a bowl of leek and potato soup and a scone or a sausage roll after a morning playing bridge.
Always with a daft "twist" on the basics or going down some rabbit hole of the latest food trends.
If your food is not great then you are in trouble anyway.
Yep.
Tis a cut-throat business.
