Don Muchos is an open air restaurant with live music in the evenings. We listened to a talented Peruvian style musician and his female vocalists entertain audiences on two separate nights. The bar serves drinks, but it's also possible to eat and watch the music. Prepare for a crowded night though. The atmosphere is bohemian in style, and there's no dress code that I could see except for the rule that fancy clothes are NOT encouraged.
Dress Code: Casual
Apparently "bars"are not as common in mexico as they are in the states. Unsure if we should pop in and have a drink, Melissa and I looked in one of the cantinas only to realize they were filled with only men. Because of Palenque's size and the fact that it seems to be more of a family town, the night life was not much to talk about.
We finally met some guys in the market and wandered to a local cantina. The only women there, we were told, had been hired by the owner to dance or talk with the men. We did not buy a single beer because the man across from our "miniature" table kept our bottles full. It wasn't until he got up to visit the mens room, that the guys who had accompanied us said it was okay to leave.
All those full bottles!!! What generosity!!
We were told it was because we were "blondes". (Melissa and I are brunette- but we knew what they meant).
So I definitely wouldn't go into a bar alone if we were unsure of the situation.
