I will be in Frankfurt for a day this Thursday, arriving at 8am and departing that evening at 9pm. Any suggestions for what to do for a day in Frankfurt? Do you recommend taking a cab to the city? Recommendations for food would be appreciated. Thanks!
Taking the train is pretty convenient. There wasn't as much to see and do in Frankfurt than I had hoped (although a couple of years ago I think I came across one or two things that I had missed) but definitely go to Rommerplatz and see the Opera House. I went up the Main Tower as well and the views were great, even though it was a cloudy day. It was windy as hell too!
