Behind the expensive run-down Royal Hotel in Phra Nakhon between the Grand Palace and Khaosan...
There is a seedy area with secondhand street sellers, cheap lovehotels, and cheaper women...
And a nice woman selling good weed at good prices. On Burana Sat Road right across from the Boonsiri Place Hotel, she has a table from 6am to 2pm. Nice woman and speaks passable English.
Some of her weed is only soso, but some is very good. Got some Gorilla Glue - nice and sticky for 5gms/800bt . Strong, smooth and sticky. Very happy...
