We stayed in Bad Nauheim for a week and found this little cafe excellent for snacks/light lunches and for morning or afternoon "Kaffee und Kuchen". (Cakes were very fresh and tasted delicious.) Location also fantastic, as directly over the road from the Tourist Office and just on the edge of the town centre on the one hand and the spa parks on the other. Unlike the reviewer who had the poor experience, we found all of the staff who served us very polite and attentive and our orders were served very promptly.The cafe is quite small (vast majority of seats outside), but I cannot think what else one could ask for in an establishment of this kind.
