Sisters Alterations is a bit hard to find on Antioch Road, in a back basement door of an office building. However, it can't be TOO hard to find because it has always been busy when I have been there. There is often a wait (especially on Saturdays) and sometimes seems chaotic. One time my item was not completed at the promised time--they were still working on it as I arrived. So, I suggest planning ahead by a day or two so you can be sure your item is ready when you need it.
