"Why so much hate? Ever since their opening, I've been a returning customer and bringing friends and colleagues along, who are all unanimous: this place makes great burgers! The pre-defined menu option as well as the do-it-yourself consistently offer variety, and the three-size system is perfect. Haven't dared to try the biggest option yet, as the normal size without fried is more than enough for a solid lunch. The Subway"-style of build-your-own (bread, sauces, toppings) works well, the meat is of high quality, and is cooked right in front of you, yet the service is very fast. Exotic options like truffle-mayonnaise or house-style bbq, 3 different kinds of onion toppings, local cheese (gruyere and luzerner, I think,) jalapenos, rucola, etc,. make for a satisfying sense of choice.Absolutely and unequivocally better than anything made in the mass market fast-food, and great value for money (and no, nothing is cheap in Switzerland.) More of these, and less of industrial food!"
