Asia - Best hotels in Kuala Lumpur

I search around and didn't find a comparison of the best Hotels in KL. So want will be your first choice? I like to stay there for a weekend from friday to sunday. I have some good rates for Ritz-Carlton, Mandarin Oriental and Shangri-La.

I have only stayed at the Sheraton Imperial and the Ritz-Carlton.
The latter has 5 F&B presentations in the club lounge but you have to ask for it. At the SI you just have cookies and snacks during the day and canapes in the evening but you can serve yourself from a small buffet.
For location, the RC is better but I prefer the spa at the SI. And I think their rooms are nicer, too.

It certainly gets my vote as the best hotel in central KL. (I still like the Putrajaya Shangri-La a bit more, but it's quite far away from the city.)
