Right.
So I was buying from the stall 20m up soi 3 on the right until I received kebabs of ridiculously high festering levels. I voted with my feet and changed brand to the one 10m down from grace hotel toward sukhumvit. All was well for a few days until I tried the "beef" one without copius amount of sauce. Rotten dog meat would have been an improvement. Currently the stall directly outside of Nana is tasting good and fresh.
