Looking for a good Tailor

I am purchasing a suit for an upcoming wedding and I am in need of a tailor to do the alterations. My experience with in-house tailoring has been decent — but most places aren't interested in giving you the near-perfect fit (close enough is good enough for them).

Do any of you have a recommendation? Preferably someone you have worked with in the past. I am considering Memorial Tailors as I have heard good things, but any information would be greatly appreciated.
