Great tour, but definitely not a food tour. Overall it was a positive experience for me but didn't quite match the description at the time I did it.
First the positives. Our guide Dimas was very friendly, enthusiastic, and a knowledgeable local. He catered the tour to our interests so we saw and learned about things we cared about. I came away feeling like I understand Viennese people and the feel of the city in general. There was also some history to explain how the people are today. The kick bikes were fun! They're kind of like larger scooters and are not electric, so you get a very small work out in and it helps to get around places faster than by foot. The food we did have was very good and we got some of it again after the tour (looking at you kasekrainer).
Now the negatives. This was not a food tour and it look 3.5 hours instead of the 2 it states. I'm all for getting more for my money, but I had a schedule because I only had a few days in Vienna (like many people); this extra length was not communicated at the beginning either. As for food, we had a small snack at the beginning (which was delicious) and then ate at one place after that where we were each given a beer (food was great here as well). After the 3 hour mark, we were offered to eat at one more interesting place but did not have the time to, so we declined. We talked a bit about Viennese cuisine, but not that much. So I don't think it lived up to the description that we would "discover the Viennese local cuisine and street food". We scratched the surface. I was hoping to stuff my face but that did not happen. Overall I think it was a good tour, but be sure to know what you're getting into. Maybe message the host to check how the tour is supposed to go because maybe ours was not according to plan. I would still give this tour a chance.
