Which tattoo shops have the picture of a marijuana leaf?

You gotta go into the gym have I think night vision or thermal not sure I forgot and go near the corner after you enter the gym activate a jet pack and fly up you'll go through the roof and you'll see a hidden shop.

There are many hidden items in San Andreas like the hidden tatoo shop in the interior universe (thats what I call it). But you have to fly to a specific spot when you go through the gym roof... I used to have a map but I'm don't know if I still have it. If I find it ill send it to ya.... Somehow.

Go to the gym in Los Santos,kill all the guys there and do the jetpack cheat. Go to the yellow arrow,fly upwards and set a marker on the map exactly 2 blocks east and fly there, you should see another yellow arrow,land on it and take your jetpack off. Once inside your jetpack may been on you,behind you or not there if it's not there just do the cheat again (don't worry this affects nothing). Then set a marker on the north-east corner of the conference building (it's somewhere near downtown Los Santos) and fly there. Once you get there you should see another yellow arrow land on it and take off your jetpack. Go inside and buy the tatoos you want then kill yourself inside the parlour.

NOTE: If you're flying in the interior universeand you see a screen that says "loading..." flash up you must load your game again, so I recommend saving before you do it.

Fly upwards in the yellow marker and then find it.

You will unlock that tattoo shop after completing 100% of the game.
