We regret that you did not enjoy your day, as we always aim to give a good experience. You visited The Wine Portfolio where you get wines from 2 top wineries, Mills Reef & Leveret Estate. You were told, while, on tour that while there are wineries, there are no vineyards in the area, because of the rich & fertile soil.
Unfortunately, as it was a statutory holiday our usual restaurant was closed for lunch so we had to use the same venue for lunch as we did for the cocktail/dessert. We apologise for the tardiness of your wife's lunch, which was beyond our control - and that she felt that her lunch, which she was able to choose from the menu, was deficient.
The choice to continue the tour, even though venues had to be substituted was perhaps unwise, but the same number of tastings & meals were given.
One of the other participants on the day has commented that it was one of the best excursions they have ever done & that they would not hesitate to recommend it, so we're a bit confused that your experiences differ so much.
