You won't find better service in any eye wear shop in the city. I've even found service at high end optical shops in NY that aren't as good as at Spectacle.
The staff are trained so well to find what you want and what will suit you. Darren + Emma are the best.
They carry only the highest quality lines made from the best acetates that will withstand a lifetime of proximity to lotions, potions, make-up & poor air quality.
They've also got a few different types of mirrors to use so you're completely clear on how things fit you.
