Costa Coffee
Costa Coffee is a Starbucks-style coffee chain with a wide selection of world coffees and pastries. At first I found it quite expensive (more than 3 euros for a simple coffee or hot chocolate) but if you compare it to Starbucks, it's much cheaper. Depending on the branch, there is a more or less extensive selection of things to eat, sometimes prepared sandwiches, but usually only croissants and pastries. If you don't like coffee you can have tea but there's only 1 type. The Brighton Costa is in the city center
