There are a few studios I really enjoy working at- they have great rooms, maintenance and exceptional equipment-
Conway Studio C- unfortunately, the SSL 9k is no longer there
Henson A or D
Studios Guillaume Tell- only there once- great place. Not great for food choices, though.
I've been to a bunch of other great places- but those are my favorites. Bad Animals was good too, but the control room was too big and the acoustics not great. The adjoining Kaye/Smith Studio 2 had a perfect control room- really tiny, lovely old API console and no reflections.
Sunset Sound 3- great desk, great acoustics, great live room.
