TANGO:

We're leaving in a couple weeks for Argentina.

We already have reservations for Esquina Carlos Gardel, but we'll have time for another show.

I understand all the tango shows are different. Three recommended shows are El Querandi, Senor Tango and Rojo Tango.

I'd appreciate any input about these shows.

Also, I'm sure my partner would love a casual neighborhood-type bar. We saw something on travelogue where people were playing guitars. Any suggestions? (Preferably with a no- to low-smoking factor.)

Thanks.
