Yes, as I recall from my various visits to the news centre, N6's 'studio door' access was via the corridor leading into the newsroom through a set of doors. The gallery itself was in the newsroom, next to where the network bulletins preparation area was.

You can see Huw going into the 2000 incarnation of the N6 studio here...

Note at 3:09, the gallery is behind Huw/ to his right with the tinted black glass.

This video also gives you a good look around stage 6 when Breakfast was still coming from N6...

That takes me back to looking at the day Breakfast moved into N6 for its short stay of two years. Contrary to what Huw had said about the studio having been relatively small, which is was of course, the trickery used to make it look very big was impressive. 

I had no idea Breakfast had a hard and soft set while in N6.

I wonder if when Huw said it was relatively small was because of the 1999-c.2002 set was on a curve and not right up to the fire lane like it is shown in the BBC Breakfast clip.
