Don't bother book through Treatwell!! The prices are different and they will ask for more cash when you get there (they don't accept card so you will need to leave your phone with them while you go to the cash machine.) The prices also don't match their price list in salon - I've been twice recently and was charged differently both times. Once was an additional £13 so very far off! Such a great nail salon, they really do an amazing job but it's a shame how inconvinient it is with the extra cash.
