The owner of our hotel (the guy was from New Jersey) in BsAs recommended Señor Tango. After he'd left the lobby, the desk clerk and I continued the conversation. I mentioned that what was most important to Mrs BamaVol (a former professional ballerina and ballet teacher) was being able to see the dancers' feet and legs. He said Señor Tango was very "Las Vegas" and unless we paid a premium price, we'd be some distance from the stage. He also mentioned a horse on stage. I'm very allergic to horses and had to leave a performance of the Royal Lippizaner Stallions last year after 20 minutes. The hotel had a huge portfolio of tango show brochures, probably more than 20 or 30, but I asked his opinion. He recommended La Ventana and I asked him to arrange it.
Cost: AR$250 pp. This included dinner and RT bus transportation between the hotel and show (very necessary after 2 bottles of wine). It did not include service, which I was unsure how to value, so left AR$50. The location was somewhere in San Telmo. The bus ride was fine except for sharing a seat with Sr. I-bathe-in-cheap-aftershave. We picked up pax at several hotels, including the Intercontinental and were the only non-Spanish speakers on the bus (Sr & Sra Aftershave were honeymooners from Peru). There were tango lessons beforehand which BamaVol Jr #3 took advantage of due to the overwhelming beauty of one of the dancers. Pre-dinner beers were AR$15 each. The venue may have held 75, but there were multiple stages I think, because I did not see any of our busmates in the room. The majority of other guests around us appeared to be from the US based on overheard conversations. We were 3 seats back from the stage. We did not pay the additional AR$100 each for seats at the stage. There was a 5 piece band that was excellent, 2 singers and 5 couples dancing. There were 2 variety acts: a man who performed one song on wooden flute and another on pan pipes (both familiar tunes) and a, for lack of better title, bolo-bouncer. The flutist was quite talented. The bolo-bouncer sucked and detracted from the overall performance. We were given a choice of menus in Spanish or English. Dinner was cruise ship quality or slightly better. There were 3-4 choices for appetizer, entree, dessert. We selected a variety: (A:warm goats cheese, empenadas E:bife de lomo, baby pork D:Profiteroles, apple stciks w/vanilla ice cream) We were allotted one bottle of wine (private label Malbec, which was decanted prior to serving) per couple. Since we were 3, we got a second bottle at no charge. The finale was a patriotic rendition of "Don't cry for me, Argentina" from Evita with lots of marching and flag-waving. Then the dancers made themselves available for a couple tangos with the guests. Mrs BamaVol and BamaVol Jr #3 danced while I took pictures. There was a professional photographer before the show who took a group photo of us entwined with the performers in tango poses. It was well done and we paid AR$40 for a copy.
