We've been to Sevilla twice. First time we took in a tableau for about 50 Euros. It was great and only thing we got with it was a glass of wine (dinner was available at an extra cost), I think it was at Arenal. The second time we went to La Casa del flamenco and it was about $18€. No dinner or drinks, but a tremendous show, so good in fact that we went back the next night (the shows change almost nightly). My son in law was with us and really didn't care to see a "dance show" but afterwards admitted that he really enjoyed it. Reserve your tickets for any of the flamenco places in advance on the internet. Sometimes tickets are sold out. At the Casa del Flamenco arrive early and line up along the rail until the show opens. There are no reserve seats and if early you can get a front row center seat. There are sometimes, some dancers performing on the streets at the plaza san fernando, and I'm told there are impromptu flamenco shows in the triana tapas bars across the river, but I am too old to stay up that late.
