As my friend's Maid of Honour, I needed to find a spa that could accommodate 4 ladies for shellac manis, 3 weeks prior to our Spa date!
Lux was the ONLY spa out of 5-6 I contacted which could do so. They promptly replied to my email inquiries - responding within 15 min of my hitting "send".
So before I even stepped in the door, I was impressed by their service.
The location is great - in the heart of Yorkville. This also means it's quite pricey. I normally am not willing to pay so much for a mani - but it was for a special occasion so I was willing to go for the best.
The shop is small, modern and very clean. Our party of 4 had great help in choosing the perfect colours for each person, and we were served hot coffee/tea as we had our manis done.
We chose the shellac manis because the wedding was a week away and we needed them to last. And last they did! My shellac mani lasted 2 full weeks - and even survived an ultimate frisbee match.
Although they do take walk-ins, you probably would want to make an appointment because the shop is small so you're taking a chance if you just pop-in without notice.
