I didn't end up joining the tour...I got lost in the maze of streets and poor signage also asked 3 separate people for directions, and arrived a few minutes after the tour start time. I went inside Mercado San Miguel and searched for 20 minutes in hopes of seeing a distinct group or someone with a Viator sign or name tag, but no one was identifiable. So, I ended up not doing the tour, and instead had a self-guided tour on my own.

The tour was great as it was a really close one-to-one experience between the guide and the three of us. Unfortunately I cannot remember her name but she was a student who was very knowledgeable about the culture and taught us a lot!

Our guide was a cute and friendly college student. The first place we went to was great -- outside in the middle of a square. We each got to order whatever drink we wanted. The food came out on a big board -- it was pre-ordered and most of us didn't care for some of the selections. Wish we could have each picked something, but not a deal breaker. The 2nd place was terrible -- it was inside a dark, empty restaurant with pictures of American movie stars and only mini-burgers on the menu. None of us ordered food. She should have made the 2nd spot a fun outdoor tapas/drinks place -- there was tons of them all around. We should have spoken up before we ordered drinks there, because we all agreed that was a terrible choice.
