I got a men's haircut from millimeter, overall the experience was good. I had to wait 10 minutes but was offered a drink so it was fine.
My stylist was nice, but didn't seem to understand how I wanted my hair cut even though I consider it to be a very standard mens professional haircut (#4 clippers on the back and side and just a trim on top).
She ended up doing her own thing which was similar and I'm not really fussy about my hair but if you are very particular it could be an issue.
