Even though this place may not look fancy, Mr Nomura is absolutely wonderful at his job. I have multiple long and short skirts, jackets and pants altered by him, some involving changing the shape of the garment completely. He did an excellent job on all of them, was never late in giving back my garments, and his price is extremely reasonable (about $10 for simple hem shortening, $20-30 for taking in waist/other more complex tasks).
By the way, he moved a couple of blocks south from his old location. The phone number is the same but I'm not sure the address is correct. It's better to call him to double-check the address if you've never been there.
