With funky interior and fortress-style exterior, W Bangkok draws attraction from younger guests (mainly Asian). It's such a weird design concept that combined purple crocodile element with Thai boxing. Maybe I'm too old for such a thing. I've been staying at the few Ws so far, this is the newest and the worst.
During my stay, I experienced the electricity black-out and poor quality food at the Kitchen. Bad breakfast selection, they have set menu for lunch which is horrifying (I still regret that I spent $15-$20 there for lunch there). They claimed it is fusion Thai food, I think it is just an absolute mess and unforgiven mistake from the kitchen. Food is very slow, you just sat there waiting for them to serve you, not so many people dine there when I was there and many staff ganged up in their open kitchen. Not sure what they were doing.
However, the Woobar is quite nice. You can feel the difference. The staff are nice and friendly, drinks are great. Food is bad since it came from the Kitchen upstairs. I guess the bar lives up to what you (at least myself) expected to see from W brand.
Although it's brand new and quite convenient (not too far from BTS Chongnonsi, there is a shortcut that you can go through to get to the Sky Train via the office building next to the hotel (Sathorn Square). The area lacks of character, just surrounded with high-rise office building. No shopping malls or they don't even have convenient stores nearby. You have to take the Sky Train for one stop to get to the shopping mall, Silom Complex (BTS Saladaeng) or two more stops to the shopping malls strip at BTS Siam station. However, this is the same train line that goes down to the river, two stops away from BTS Taksin where there are piers that you can on board either water taxis or hotel shuttle boats to hotels located on the Chao Phraya river.
I DEFINITELY WILL NOT RETURN, may come for drinks at Woobar or maybe not since there are many great places in the city e.g. Vertigo moon bar at the Banyan Tree hotel.
BTW Nice (weird) pool but relatively small.
