Three of us booked “the taste my Swiss City Lugano.” We took the voucher and accompanying print out to our first stop, Bottegone del vino. We presented the documentation. We were seated at a table served a light lunch and lovely glass of wine. We were then given a b”” for 115 euros. We presented the voucher again...along with the print out listing their restaurant, the waiter took it, discussed it with three others. The manager then brought it back to us removing 15 euros for the wine and chastised us that we should have presented it first? We did! So after paying over $200 for the “free” tasting we had to pay 110 euros. It was very clear victor had doneeither a poor job selecting the stops or partnering with them so they understand their responsibility. We want our money back! We did not pursue the other stops....it was just too expensive and uncomfortable! I am trying to reach viator now to get a refund. They don’t make it easy to reach them. This is the first site I found to complain.
