Heidi was a great guide. Our first stop was at the famous Din Tai Fung where her husband had already reserved our spot in line in order to avoid a long wait. She greeted us with some of Taiwan's famous bubble tea. We spent a fun evening with Heidi and her husband. My only regret is that we filled up on dumplings so we didn't have much room in our stomachs for all the food.
Heidi was very flexible and adjusted the tour to our food tastes. She also gave us a lot of extra tourist tips for the rest of our stay in Taipei and even checked to see how we were doing a few days after our tour! The tour is a bit pricey but I would recommend Heidi as a guide.
