I've been to Embros - good but slow service. Nikolaou - they won't touch anything but "regular" knives (i.e., no serrated, no santoku, etc).
In a pinch, I've been to Personal Edge, that mall store.
Where do you get yours done?
(Please don't tell me to sharpen them myself. I do have the Japanese waterstone, but I'm not sure if I'm doing it right...)
