Good for basic alteration jobs. they are relatively prompt and being close to me and working mall hours is an advantage.
I did have one unsatisfactory experience when I requested extra thread to reinforce a high stress point on the inseam of one of my pants and also to double wrap the button which comes off periodically - I assured them I did't care if it didn't look original or made the button stiff - but they just ignored instructions, did it the usual way and the same item needed repair again in 5 months. ( next time I took it to Sketchley Cleaners in the same mall, the older Korean lady did exactly what I asked and it's still holding up 2.5 years later,,,)
But overall they're pretty reliable for routine work like hemming pants, adjusting waists or replacing buttons in good time and reasonable price.
