Sevilla was a great experience for us. We went to the Salsa dinner show. We had a table right in front. The show was also very nice.
The food was very good, but make sure it's something you'll be able to eat. The menu is fixed for the dinner shows, so you won't be able to order from the menu. My husband wasn't able to eat the fish, but they were able to accommodate him with beef medallions for an additional $5. You should try the sangria while there. It's a bit sweet though, so don't order it if you don't like sugary drinks.
The $36 only covered the show and dinner. Any drinks or appetizers were extra, so I'd have to say it was a bit on the pricey side.
