Best burger in the world I had last week at a local Texas Longhorn in Stockholm (http://www.texaslonghorn.se/restaurant/sickla/) - there are altogether 30 Texas Longhorn restaurants in Sweden. First one was founded in 1994 by Texan/Swede Philip Huntzinger.
I had the Smokehouse burger with bacon, cheddar cheese and the Texas Longhorn Steak Sauce together with crispy onion rings - delicious!!
