So far Grandaddy house has the best combination of quality, price and service that I've found from the 6 or 7 dispensaries i've purchased from in Pattaya.
I would probably give 4.5 stars as it doesnt have the biggest selection (maybe that will change) but I tried Bluewalker and Mimosa and in a city with a lot of top-shelf weed, these 2 are near the top and would be about 100bt a gram cheaper than comparable products elsewhere.
Positives: Excellent weed (even by premium standards) Fast service and delivery, Best price to quality ratio
Cons: Was only 3 strains on the menu so if that changes..I'll gladly update my review.
Note: Only had delivery so cant report on the dine-in (smoke-in?) experience.
