Behind the diamond lattice windows of the Keller you will find beautifully laid tables, wooden furniture and paintings on the walls. The menu offers a selection of quality international cuisine including Keller's Krüstchen (a slice of bread served with schnitzel, fried egg, mushrooms and roast potatoes). Alternatively you can try a delicious Spanish dish such as Andalusian fisherman's stew (grilled game fish served with Mediterranean vegetables and curried rice). There is also a good selection of wine and a small selection of meals for vegetarians. The restaurant has two dining areas and is popular with hotel guests, day-trippers and couples. The highlight of the week is the Sunday menu which is a big hit with families.
