Till you find a good one go to Beer Point in Pratamnak Soi 6 almost down at the end the soi before the corner.
I had a Belgian unfiltered and I saw IPA also, all draft ....
Try Beer Point in Pratamnak Soi 6 almost down at the end, they have a nice variety of beers, from Belgian unfiltered, IPA, German dark over to a wheat beer.
Maybe friday it's crowded - you get chicken wings for free to your beer ...
