The Federal Hotel on Jalan Bukit Bintang is quite an historic building,when it was built in-time for Independence celebrations in 1957 it was the tallest building in Kuala Lumpur!
The second block with the revolving restaurant was built later as was the (now closed) bowling alley.
There is an Irish Pub,Delaney's on the side of the building that has one of the shortest Happy-Hour's in town until 8pm...I mean come-on,why bother?
It's fairly austere and barren inside and the times I've been there,it's a bit devoid of atmosphere save for a couple of drunks singing along to the band....
It's a sort of community pub,you could imagine it in a small Irish village where everyone knows each other.
If you get bored talking there are mags and newspapers to read and the ubiquitous large screen tv for the essential EPL games.
The food is good but pricey and is failry typical (stews,pies,fish and chips) and nothing special. All-in-all not really worth visiting unless you happen to be staying at the Federal Hotel and are too lazy to walk to Changkat Bukit Bintang,or you've just bought the latest IT gadget from Low Yat Plaza (behind) and need a couple of lunchtime beers.
