Like 100ber said above, it's better to use pesos for dining in the local restaurants.
Also, as he mentioned, the in-house exchange rates are also favorable. For example, Hong Kong has their in house exchange rate set to 17 to 1, even though the peso has been ranging between 18 to 21 to 1 in recent months. So, you are better off paying in pesos at most of the puta bars.
However, one caveat. If you are going to pay for ficha drinks, your drinks, etc. in pesos, know the price in advance. For example, at Hong Kong, a ficha drink is $9 U.S. or 153 pesos, using HK's 17 to 1 exchange rate. It's a better deal to pay in pesos, but be careful you don't get overcharged if you are drunk or if you get a crooked mesero.
Also, have the right amount of pesos for the tip too. Otherwise, you might actually wind up paying more, if you don't have the correct denomination and wind up overtipping. Unless you are very experienced using pesos, it might just be easier to stick to dollars, for the little bit that you'll save, so you don't miscalculate or get ripped off.
It's really easy to just give them a $10 bill for the ficha drink with a tip. Or, to give $5 for your beer, with a tip.
Not open to outside investment? I've been standing in line for a month behind fifty other people, because we were all told we could get in on your organization on the ground floor. Guess I'll have to tear up my check. More money to spend at the Las Vegas TUSCL meetup!
