I visited a Casa Partagas in Playa about 3 years ago. The smokes I looked at/bought were legit. The lady helping me did have some misinformation when describing some of the cigars I was inquiring about, which made me suspicious. But upon lighting, there was no doubt to provenance. Expensive? Yes. But I figured it was worth the price, given the situation I was in. I'm not in Mexico very often (about once a decade).
I wish I could tell you what the shop looked like from the outside, but apparently my photographic memory doesn't go that far back.
