Can only comment on the female haircut option since that's what I got today - 5/5! Today was my first time at Hair Story, recommended to me by a friend from university who comes regularly for trims and haircuts as it's located so close to UofT and is so affordable.
It's located on Yonge Street, just north of Wellesley Street and not that hard to spot. No private parking though. It's actually really spacious inside the salon and lots of natural lighting. A lot less nicer in terms of interior design than say, Seefu, but still very organized and clean. There is a cleaner constantly patrolling around the stations, sweeping. If you're looking for a mid-tier, no-frills Asian hair salon at 1/2 the price of swankier ones, like Seefu or N15, Hair Story is perfect for you! But seriously, my bill came to $35 for a female haircut + wash + styling (curls), which is the cheapest option I've seen so far downtown (vs. Kamiya, Seefu, N15, H2GOA, Hair District, etc.) not counting the ratchet Chinatown salons.
I booked in advance and asked for Anna, who has been consistently recommended by fellow Yelpers. Anna is really cool; she speaks Korean and her English is not perfect (i.e. she might not catch some of your slang or jokes), but not at all a hindrance to her work. She hung up my jacket and scarf for me, and was very patient when I showed her all the photos I've collected of my desired haircut. She also works really fast - my entire appointment lasted 30 mins max! Most of the stylists here seem to be Korean, which is awesome. Based on what I saw today, they also do amazing male haircuts.
They do take credit and debit cards, but tips are only accepted in cash.
100% would recommend and will be back again for future haircuts!
