This has been discussed several times here. Over the past 2 1/2 years that I have lived in San Pedro there has been a couple of MPs but both are closed. There is a Tico night spot 'D'pelufos' that has a lesbian show and at times can be fairly good (in terms of chicas). There is almost always a lot of working chicas in the Mall shoping (spending all that gringo dinero)jejeje, in the mornings/early afternoon. But be prepared--they do not look the same as when working and often they will be with their K*ds or other family members who frequently do not know what they do.
Nice thing is that from the mall de San Pedro, it is only a 5-10 minute ride (bus or taxi) to the gulch, the SL, or the 12 MPs in the area south of the REY.
OH! and there is a beauty salon where the chica working there (the owner) offers masajes with a very happy ending!!!! She loves sex, but does not offer it to every customer (most I think).
