Will be spending four days solo in Frankfurt prior to joining friends to travel around Germany, Austria and Switzerland. This will be my first time in Frankfurt but have traveled to the three aforementioned countries many times.
1 - Are there any must see sites in/near Frankfurt that tend to escape attention or support in the travel guidebooks? My interests are wide open. I would be able to take a train/bus up to about 1 1/2 hours away. Already have a full day planned for Nuremberg as well as a full schedule of stops in Bavaria later in my stay.
2 - Any family owned/operated food establishments or locations popular with the non tourist with delicious, hot food for lunch or dinner (in Frankfurt). I enjoy many types of food but prefer local dishes.
Thanks for any suggestions.
