While we’re on the subject of burgers, Café Latitude makes a rather nice one. Located in the Mövenpick hotel by the airport, Café Latitude is an appropriate venue for business and informal lunches alike. Their breakfast buffet is also very good and reasonably priced.
Pictured below: a cheeseburger accompanied by a small cole slaw salad and the standard side of fries. The fries, though not home-made, were quite nice. However I still very much feel some innovation is in order in that regard.
