Thank you for the report!
I have been to HK I think 7 or 8 times over the last 20 years and I have never stayed at the MO and I think this report supports that. The rooms itself do not look particulatly exciting and you do not need to be a guest to enjoy the bars / restaurants. I have visited a few over the years and always enjoyed the atmosphere, good service etc (by the way, what is the name of the bar on the top floor? I cannot remember now but I have had some very good whiskey there). I do love a hotel with a barber in it, always get at least a shave!
I still think that for tourists at least the first stay needs to be at IC / Pen (or maybe Rosewood now? Have not been since it opened), and then from then on I have stayed at either FS, TUH or LMO each with their own pros / cons but to me look squarely better than an actual stay at MO.
