The restaurant was opened by Chris Israel in late 2009, and closed after December 31, 2015.[3] Grüner's mainstay burger, dubbed "The Hambürger", was thought by many to be Portland's best, and it was reintroduced at The Loyal Legion when the former Executive Chef of Grüner took over that venue's bar.[5] The restaurant also served bratwurst, pretzel-wrapped weisswurst, saucisson sausage, sauerkraut, gold potatoes, and sweet-hot mustard.[6] The drink menu included German-style beers.[3]
Kask
Grüner's attached bar, Kask, was named one of the top five cocktail bars in the city by the Drink Spirits magazine,[7] and initially remained open following Grüner's closure.[3] Kask was given a four star rating by the Difford's Guide in 2014.[8] It has since closed, and Icarus has moved into the space.[9]
