I used to go to Maya (another Korean hair salon) down the street, but got tired of the loooooooong wait even though I always made an "appointment".
Goa has the same pricing for haircuts ($25+ for women), and I like my haircuts slightly better here. They also have a customer loyalty program, and give 15% back on your next visit if you remember to keep your card.
In the past, I have paid $85+ for haircuts at high-end salons and left unhappy. In contrast, at Goa I get a very reasonably-priced haircut that doesn't take hours (because Hannah is gooood) and leave happy each time.
