I will have a four hour layover in KUL next month and I am trying to determine whether it is worth it and feasible to take the KLIA Expres into the city for dinner (time frame is a 5:50P arrival with a 9:45P departure). From what I have read on the these forums and the Expres website, it runs at 15 minute intervals, takes ~ 30 minutes and is very reliable. With that, passing through immigration (only hand luggage), checking back in and (worst case) just missing trains on either end, I could have about two hours in the city.

I have never been to the city, but if were possible, would be interested to take the train into the city as I have never been there. Obviously I will not have time to do anything but have a light meal and walk around. Also, I understand that it will be nightfall in a city that I have no experience in and certainly will not know my way around.

I guess what I am asking is, is there anything around KL Central that I can do to pass a couple of hours. Are there any good local cuisine restaurants in that area? Or, should I just pass the time at the airport?

I have transited through KUL before and while I found it to be a very nice airport, I don't know that I would be able to find interesting things to do for the four hours. I will have access to Star Lounges as I will be traveling on a International F ticket, and my cursory knowledge leads me to believe that that means the Singapore and Thai lounges and I have read that the SQ lounge is not among their best. Incidentally, if I choose to transit into the city, would either of the lounges allow me to leave my carry-on baggage there so I do not have to carry it with?

Of course, all of this assumes that my arrival to KUL is on time, but for the sake of this, I will assume that to be the case.

Thanks in advance for any thoughts or ideas.
