The plus of a banquette is it takes less room than moving chairs....so yes there's room.

If you want to keep a chandelier in the same place and have it centered over the table, that is something else to consider too.

Centered under the light, tape off on the floor the measurements the sized table you want. Then start playing around with chairs against the wall to approximate how much room you have between the wall and where the edge of the table hits.

Also consider if you want a banquet with people leaning up against a glass window. I know plenty of people do it. I *hate* sitting at my friend's banquet that is up against a window. I feel like I am going to crash through it.
