You do miss quite a bit of anything that happens in the recessed part of the stage. This is a small, cozy theater and so while these seats put you close to the stage I feel like no seats are going to feel too far away. Look for seats in center.
Seat is on the extreme right side of the stage, but the stage extends out over the orchestra pit and most of the action happens there, so it isn't as terrible as it looks. You are very close to the stage and action, but I do think there are better seats.
