2.5 stars. I hesitated to leave only two but I really do feel this an "I've experienced better" salon.
Aesthetically, it is a definite step-up from its neighbors. The other Koreatown nail salons tend to smell really bad (I hate writing this, but its true) and are terrible at honoring appointments or managing walk-ins. Beyond Beauty, on the other hand, has a very professional appointment system and an atmosphere I'd compare to The Ten Spot or a Yorkville nail bar. There is a coffee machine and a nice clean couch in the entry vestibule.
The manicures, pedicures, and shellac are a little better than their competitors', but that is partially owing to the nicer environment and the neater, more streamlined bottles of nail polish.
I do NOT, personally, recommend their lash services. I am Caucasian with long and thick but straight lashes. Their lash lift/perm kits do not seem to be made to flatter a variety of eye shapes and natural lash types, but rather seem best suited to short sparse Asian lashes. Their eyelash extensions tend to look very fake... not natural and fluttery, but more like strip lashes.
Maybe they like it that way, but let's put it this way. If EVERY breast augmentation a surgeon does looks like tennis balls, you may question his skill and versatility.
I've been 3 or 4 times and tried to communicate what I want differently/unlike before/unlike other clients, but I've also had trouble with the language barrier between me and the technician(s). I had a very hard time explaining what I liked and wanted to one technician who spoke very little English. Not a big deal with a pedi, but definitely a big deal with my eyes!
This is particularly annoying because their website actually STATES they are skilled in designing lashes to flatter the individual eye.
Anyways, your mileage may vary.
