I'm surprised to be the first to review Effeto Donna!
I found this place through Google. I moved to TO from Vancouver and wanted to find a waxing spot as good as I was used to (Sugarbox). I called around and asked if they had a "no-double-dip" policy, which they do.
Effeto Donna is a small little spot above Bay Station. It is clean, they do NOT double dip, the girls wear gloves and all and all it's a fine place to get waxed.
Best part is the price point: Full Brazilian for $35. Relatively painless and you're in & out in 20 mins.
Mona is my favourite girl there. She is friendly and funny. I've been about 5 times and will continue to get my waxing done there.
