If you've not heard of it, the Swedish tradition of fika is simply about taking time in the afternoon to sit and drink a coffee or two, with a slice of cake or a sandwich. If that sounds like your kind of thing, get down to Scandi Kitchen in Great Titchfield Street, where alongside your coffee, you can order a smorgasbord to share, meatballs, or a Nordic-style open-faced sandwich on rye bread.
