It was my first time seeing a show there and I've done loads of research beforehand, to make sure I got a good seat. Eventually I decided on row 19, seats 13/11 and was not disappointed. Great view and acoustics! Having been there now, I think almost every seat could be a good choice though as the theatre is quite small and intimate. The seats are very narrow and close to the next person so there's not a lot of space (especially leg space), they're also not the most comfortable (but good for the length of the show).
The theatre itself is very beautiful, well preserved and the staff was also very friendly. I'd definitely come back again for a good show!
As for the Lion King: I absolutely loved it! The actors, their voices and especially the costumes were amazing. Absolutely worth seeing!
