We read plenty of reviews prior to taking this trip, and mostly the reviews were positive. The one thing that we saw sticking out as a negative was that "there isn't enough food". I disagree, at least for the Near North tour that we took. The first stop, a Jewish deli, gave us half a sandwich with a hearty amount of fantastic pastrami. The next stop was right around the corner, so there was very little time to digest the sandwich. The next stop was a huge slice of Lou Malnati's famous Chicago pizza. It was amazing. Since the two heavy stops were back to back, it was *almost* too much food. I was pretty full after just that (and I am a 240lb guy). The next several stops were a lot lighter. We got an Iced Tea at Teagschwendner, which was perfect for the super hot day. There was a decent amount of walking after the tea, so that gave us plenty of time to burn off some of the pizza and pastrami. After the walk, and discussion of the Playboy mansion, we tasted some spices and cinnamon at the spice shop, and some oil and vinegar at the oil place. By this point it had been a while since we had any actual food, so the butter toffee at the Fudge Pot was not at all intruding on my stomach space. We then walked quite a bit more before our final stop at the bakery.
Our tour guide (Angie) was very knowledgeable and personable. During the walks she made an effort to chat with each couple on the tour and connect with us. After the tour was over, we ended up walking the tour in reverse, and buying stuff at several of the shops. We bought kolachkis from the bakery, lots of tea from Teagschwendner (the staff there were great), and butter toffee from the Fudge Pot.
We also read one review that said "bring water, they won't let you buy any and they don't give you any". This also turned out to be false. I still recommend bringing a bottle of water since there are some long walking gaps between stops, but every place we went had at least a water cooler or the ability to buy a beverage. Lou Malnati's gave us each a glass of water with a refill pitcher at our table.
If we end up in Chicago again, we plan on checking out one of the other tours since we liked this one so much.
