Frame Place

I like NuNu gallery on Union.

I used a place on Flatbush (I'm fairly sure it's on Prospect Place corner)... there is a cafe next door. They were very nice and did a great job. Remember that if the picture is going into a bathroom, tell them. It will be sealed up better than normal to keep out water.

That framer on Flatbush and Prospect is named Artisan. Unfortunately I can't recommend their work. I brought a rare movie poster there and they damaged the border of it. I was able to minimize the damage but, yk, the damage was done. Also, the couple other prints/posters I had framed there shifted and slipped out of position after a year or so. That said they were very nice!
This was before they split their space in half to make room for the cafe so maybe they have changed hands/personnel.
If having really good work done is more important than saving a few $ I highly recommend Make-A-Frame on Atlantic across from Sahadi's near Court. (I know, a bit of a hike if you're carless.) They aren't the cheapest, nor are they the most expensive, but they do great work and have great ideas about what sort of frame will match your piece.
