La Nouba is one of my 8 year old daughter's favorite things. As a result, we see it quite frequently. It's almost too embarassing to admit to how frequently.
We like to see the show from many different angles. Now, I nearly always book Category One seats in the lower section.
But, for a first-time viewing of the show; espcecially if it will be a once in a lifetime chance at seeing it, I would recommend a seat in the first few rows of the upper section, preferably in section 204. Rows AA to DD are Category One (the more expensive). If you want to see the show for a little less money, Row EE Section 204 is probably the best deal in the house.
From there, you'll get the full perspective of all the action that takes place. And, as others have said, there is a lot of action going on at any one time.
Very few people walk away from La Nouba disappointed.
