Found this on another website, but thought some of you might want to check it out.
Its a new cocktail bar, opened a few nights ago, with good music (I think they have guest DJ's all the time), but not crowded. It obviously takes its name from the Bar counter and lighting theme - an acrylic bar top, that 'glows' different colours from leds running through it - really relaxing and chillout effect. Also there are couches, and bed type couches in it. A really relaxed/chill out place with the best cocktail menu I have seen in BKK. The main bar staff are ex-Q Bar and can mix better drinks than I have had anywhere. Up till now my fav cocktails were in the steak house on 2nd floor in The Mariott, and Syn at the Nai Lert, but Glow makes a better Cosmopolitan than I have had anywhere! I like Q-Bar, but find it a bit crowded, and a bit same old - same old. If you like a good bar with good music and good (strong) drinks give glow a try. Prices are resonable (lower than similar places), and they also but on comp Tapas, and do bar snacks. Defo a place I will be going back to. If you Like Syn, Q-Bar etc, you will love it here!
