Viva, Sukhumvit Soi 8; The Sportsman, Soi 13; Breakers Live, Soi 13; O'shea's, The Robin Hood and The Royal Oak in Soi 31/1 and a place directly opposite 7-Heaven in a small sub-soi off Soi 33 for starters.
In terms of quality, as they all come from the same place and sell out very quickly, there's practically no difference. I'd guess that all the other places that have it are much the same, the biggest difference being the type of place that you're looking for.
