In Harem, the girls 6 to 9. Very friendly; varying degrees of aggressiveness, lots of women - no waiting! No english speaking the night I was there- but it did not matter. They will dance in the bar for you for just drinks... Cost for beer for you 25 pesos; cost for drinks for girls range from 50 to 100 pesos depending on what she drinks, but they didn't push it... I have been there several times and the most I bought was 2 drinks in a 4 hour period... Cost for full contact dance upstairs is 50 pesos (~5 minutes); cost for FS 450 pesos (15 minutes give or take).
Excalibur, there were 4 absolute fun loving 9's the night I was there... along with a half a dozen 6-8's. Very few locals the 2 times I was there, also not crwded - no trouble getting attentions! Again, dances in the bar - no cost... Dance upstairs, 200 pesos, FS upstairs in a private room was 1000 peso for 30 minutes... anything goes. Drinks were more expensive - there is one that they tried to charge 250 pesos for, but the girls didn't push it there either.
I have also been to Poisson's Mens Club - more women, more english speaking, but about 2X the price of Excalibur - a little more private & selection...
I've heard a lot of good things about Pasquareles also - supposed to be on par with the Harem - but the one time I was there (Wednesday night), the talent wasn't so good... Also- Harem, Excalibur, Pasquareles - is no cover...
As I said, I haven't been to Infinito, Givenchy, Matehuala, but I've enjoyed other locations...
