I will not take my clothing anywhere else.
I've had 6 or 7 items altered and each time I'm amazed at how clean and professional the results are. I've bought pants at The Men's Wearhouse and had them hemmed in store, and the results looked amateur compared to what Lisa's Alterations can do. I even brought in a pair of designer jeans with a unique wide, double-stitched hem and when I got them back I could barely tell that they had been altered.
As another reviewer mentioned, the prices aren't super cheap, but rather about average. They don't try to gain clientele by undercutting the competition; they do it via great service and word-of-mouth. If you ask me, that's what you'd want in a tailor.
