I stopped into this shop while on a cruise last week. It is located on the main street (Av. Rafael E. Melgar) that runs along the port and is near the intersection of another main street called Calle Juarez. I asked a few locals and shop owners where to find Calle Juarez, and they were able to point me in the right direction. The shop turned out to be about 7 blocks north of where our boat docked. We docked right where there is an overpass that crosses Av. Melgar to an elevated shopping mall. You have to come down an escalator to Av. Melgar. The shop is on the side of the street across from the ocean. It is above a bar called Fat Tuesdays. You go in a door at street level and up some stairs.
We got there about 9:30 am and it appeared to be closed. A couple of guys were standing around in front of the door, and one asked me, "Cigars?" I thought it was going to be another fake cuban cigar scam, but he turned and unlocked the door and invited me up. The place was officiallly still closed - the lights were out and the chairs were up on the tables - but he turned on the lights, opened the humidor and let me in to chose what I wanted. The hygrometer read 63% humidity, so they were well cared for.
Pretty good selection, and looks like it would be a great place to smoke, but we were off to snorkel so I had to get back to the ship. Bought a couple of Boli RCs and a couple of RASS to smoke on board, as we only had two days left on the cruise. Prices are what you would expect - very high. Especially in comparison to the first shop I stopped at when looking for directions. It was a souvenir shop, and they had a cabinet (not humidor) filled with various "cuban" cigars with a sign that said "Any Cuban cigar - $6" You get what you pay for.
As I was walking back to the ship, some guy in an alley asked me if I wanted to buy some cuban cigars. I said I already had some and showed him what I had purchased. He replied, Wow - those look really good!" It was pretty funny.
We also stopped in Rohatan, and there was a guy rolling cigars on the dock and selling them for $3. I figured it was a better souvenir than another t shirt and cheap enough so I bought one, and it turned out to be a really good cigar.
