The main store is a little over-priced, so I'd give it 3 stars. They have a great selection but my hairspray here is $18 and $12 at other places.
I'd give the Benefit brow bar 5 stars because of Valerie. She clearly knows her brows and listens to what you want, as well as giving her own advice. I brought a friend in from overseas and she found time to squeeze her in, even though she knew she clearly wouldn't be a repeat customer as she lives abroad. This to me shows great customer service and I really appreciated it. I will be going to Valerie from now on.
