Time Out says
An informal café on Great Portland Street, Portland Café has been around since 2010, serving deli items, sandwiches, freshly-baked breads and pastries alongside herbal teas and coffee.
Breakfast is available, too. Expect options such as bacon and sausage sandwiches, full English breakfasts, scrambled eggs with toast, organic muesli and porridge. Lunchtime options include jacket potatoes, generously filled sandwiches, pasta dishes and soups.
