It's a fantastic place. I shop for weed here all the time. Being customer for 2 years. It's not overpriced as other shops. You can get good stuff even for 100 baht a gram
The price is the cheapest in Bangkok and they do have a lot strains and they grade them from 1a to 5a with 5a the strongest and most expensive.
My first trip was well worth it but can't remember the strain. The second time they had not 5a bud.
I would come back but it is a long walk from main road so take the local taxi motorcycle
