The Korner http://www.gourmetburger.ch/ is one of Zurich well regarded Burger Bars and has an outstanding set of beers to pick from. The burger menu is rich in variety and they also have a few option with their fries.
The Burger choices are varied with options of Lamb, Chicken and then a wide variety of extras and combinations. There is of course a vegetarian option.
The burger is served with a nice size sesame bun and I opted for the more traditional burger with the condiments of salad, tomato, pickle and Cheddar cheese. The burger patty was a very generous size and cooked fresh with a nice smokey flavor to it. The one thing that did not rate well for me, was the consistency of the Burger patty, which was beef but with a mix of some pork meat which diluted the beefiness of the taste and gave it more a sausage taste then that pure beef flavor. To me it honestly did not feel like a burger but more that mixed meat patty taste which is nice, but not a burger taste in my opinion. This was disappointing. It is a shame as the atmosphere, decor and service are wonderful. The selection of beers is impressive and the choices of special sauces available was nice, and the straw fries we had were excellent. This issue with the patty is something that I am discovering here in Switzerland that it seems to be the style of the meat patty a more mix cut of ground beef than one single selection.... will have to now try some new locations and see if this is the case or just a one off.
Restless Hamburger gives the Korner a 6 for their Burger.
