Four Seasons is in a great location and seems like a fine place for dry cleaning or alterations as it's been around for a while and has a very nice looking storefront, but don't be fooled. I'm giving the review 2 stars instead of 1 because the shirt laundry I've had done there wasn't awful, but the alterations were terrible.
I recently went to have a blazer and a shirt tailored. I received the blazer back and the sleeves were too short and the buttons were sewn on so poorly they fell right off. As for the shirt, the sleeves were also much too short and they didn't even trim any of the excess thread off after they used the sewing machine - there was a solid foot of several strands of thread hanging off from one of the sleeves. It looked as if the shirt was done in a complete rush with no attention to detail.
Needless to say I will be taking my future dry-cleaning/shirt laundry and alterations elsewhere.
