I just came back from a trip to Buenos Aires and thought I would provide details that might be informative to anyone who's considering playing when they're there. I was there for 10 days, and spent about four hours at Casino Puerto Madero. I'm basically writing the post that I wish was written (and I had read) before I went to the casino.

The casino itself:
-There doesn't appear to be a formal dress code at the casino. I was wearing flip-flops and it wasn't an issue. If you have a camera (I did) they will make you check it. They didn't make me check my iphone though.
-You can exchange U.S. dollars at a little both right after security. When I was there the correct exchange rate was 3.8 pesos/U.S. dollar, and the rate they gave was 3.7. The rate at the neighborhood money exchanger was 3.75, but they aren't open outside of regular business hours (which in Buenos Aires means half days on Saturdays and not at all on Sundays).
-Unlike many other casinos, most employee don't speak English. Don't assume that they should (you're in Argentina, after all) unless you want to annoy people.

Poker at the casino:
-There are poker tables on both the second and third floor. The third floor was 25/50, and the second floor had 5/10. There might have been lower limits but I had no interest in anything lower than 5/10.
-Cigarette/cigar smoking is allowed, and is rampant. If you don't like smoke, you'll want to shower if you're there for more than 30 minutes.
-The rake is an UNCAPPED 5% of the pot. I found this to be a little ridiculous since I play in the States.
-Tipping is less common. At my table, if a tip was given, it was at most two pesos, even for large pots.
-I wasn't allowed to wear my hat with the brim facing forward. I was, however, told that I could wear it backwards. Why, I don't know.
-During hands, English isn't permitted. If you don't speak Spanish it's not a huge concern, but it's a good idea to learn your numbers. It'll make things easier to understand.
-At the table, you play for two hour periods. You can leave during this time, but there are no seat changes. After the two hours is up, they ask everyone seated if they want to stay for another two hours. Everyone is required to get up. During this time I think they empty out the rake. When the players return they draw for seats.
-Players didn't seem very good. One guy failed to raise the nuts on the river, for example.

Another thing: I took a trip to Iguazu to see the falls (which are very pretty, incidentally) and heard about a casino there. I almost went because I heard they had poker, but when I called they said they were having some kind of tournament and weren't spreading any cash games. So I'd call before visiting the Iguazu casino, but know that as far as I know they do usually have poker games happening.

Thanks for the post. Am thinking about a trip there, and wondered about the poker scene. Anyone know of other poker rooms in BA or in Uruguay (Montevideo, Punta del Este)?

How is the scene in BSAS rn for NLHE?
