Your walking tour starts at 12:30 PM from the Alexander Nevsky Cathedral. From there, your guide will take you around all of the interesting sites in the center of Sofia. You will visit sites such as the Cathedral, the Basilica, the Presidency, the Rotunda, the Roman heritage, and more. They will also tell you about the history of the sites, as well as about the overall history of Sofia and Bulgaria.
While you enjoy the sightseeing tour, your guide will also take you to some “hidden” places, which you would have difficulty finding on your own. In these places you will have the chance to try some of the most famous Bulgarian drinks and foods such as ayran: a salty yoghurt drink, banithsa: pastry with white cheese, shopksa salad: a traditional Bulgarian salad with tomatoes and cucumbers, local meze, home-style bread, local beer, and some sweets.
Overall there are 3 stops for such food tastings, and generally the food is enough to get you satisfied. The tour eventually ends between 3:30 PM - 4:00 PM next to the covered market, near the Serdica metro station in the city center.
