Founded by entrepreneur Tomas Tómasson, this small chain of Icelandic ‘burger joints’ is now making a name for itself in London – although diminutive Tommi’s feels more like America than the icy north with its bare brick walls, movie posters and stateside memorabilia. The kitchen makes use of a US charcoal grill, but their beef is Aberdeen Angus and buns are sourced from a local baker. Intriguing monthly specials add variety to the short menu, and punters have unbridled access to the relish tray for personal burger-pimping – check out the special Icelandic ‘cocktail sauce’ (used like ketchup in the home country). Imported Icelandic ice creams and Viking beer also strike a patriotic note, and service comes with a big smile. Tommi’s is reckoned to be amazing value too – “you can get a meal for less than a tenner”, raved one fan.
