We stumbled upon Ergon Deli & Cafe accidentally walking through Mayfair really hungry one afternoon but wanted to include it in our JAM's London morning. It's Greek food at its finest. Don't forget to order their pancakes smothered with delicious Greek yogurt as if it was icing on a cake and then a mountain of berries, honey and granola. There were authentic savory dishes as well along with the best coffee, handpicked wine selection and their own Greek deli items for sale.
