Flew for the first time in F on a paid ticket (QF1/2) back in March so I'll add my 2 cents about the SIN lounge here.
No escort after I entered (unlike SYD) but I was taken to the dining area up the back on the left (as circled in the image below) after I showed my BP to a waiter. I don't recall being given a special menu but I can confirm I received one when I was in the SYD F lounge on the way up. The tables in the alcoves where I was were pretty full, but the area opposite me near the windows were fairly empty.
My flight was on a Thursday night and the area where the sofa style seats are were packed. Had to wait over 60 minutes for a shower to become available, and luckily I was able to use one about 15 minutes before the stated boarding time.

		 the food and drink you consume over 4+ hours in the lounge is worth a multiple of that said ticket
