Might be a bit far for you, but we've been happy with Snowball's Pets Grooming Salon on the UWS and have encountered other standard poodles around here that are groomed by them as well. I'm definitely not a grooming connoisseur but we switched to them after we felt the first place we tried did only a so-so job (and added random extra charges - e.g. for grooming our dog's feet). Snowball's does a very nice job, charges fairly, and our dog seems to like the groomer well enough.
(I guess I should add that the slightly scruffy poodle face in my profile pic is pre-grooming)
