Daisy is absolutely worth it!! The girls are super nice and very accommodating to what you request of them. For $20 I got a shellac colour change and the lady (I didn't get her name) cut and filed my nails as well. She was very meticulous about having each nail the same length and in the same shape as well.
I showed her a colour that I wanted on my phone and she went searching through the store to find the right colour for me! That's what I call customer service. Even though she was very careful, she finished within 45 minutes.
I would definitely recommend calling in advance to book an appointment. The store gets quite busy, especially after 5pm on a weekday. I went on a Thursday at 5:15 and all their seats were taken up and half of their pedicure seats were filled.
I would be weary of parking though. You can't park along Yonge street during rush hour! The store takes cash, and debit only if it's a transaction of $10 or more.
