I came here once for high tea and was really disappointed. The high tea for someone with food intolerances was no where close to as good as the one for people without food intolerances. I received very little food was still hungry after. My gluten and dairy free high tea was not worth the $75 I paid after tax and tip (I did get a glass of prosecco). I would give the high tea experience one star.
On a high note, I attended a private event at the Windsor and the atmosphere was really great. The ambiance was really nice and all of the guests seemed to have had a good time. One friend and I asked to see the main dining hall as we arrived late and the server followed us the entire time. This experience made me feel slightly uncomfortable. Allover, I would give renting out the Windsor and hosting a private function a three star rating.
