I have three suits by Spiros and they all fabulous and are, in my experience, of better quality than other tailors I've used in Toronto. Pricing is better too, which is less of a concern than quality of craftsmanship and fit, in my opinion.
For those citing issues over direction in other reviews, I also found that he took direction well from both me and the designer, except for when I requested something that he said was not going to look flattering on my current physique. As a result of taking his advice, I no longer blow the crotches out on my suits.
