I wonder if Nog ever forgot he was living in a holodeck and went to the bathroom in Vic's hotel.

As there are several episodes where characters are trapped in a holodeck simulation for a considerable length of time, I presume the plumbing works. ;)

I would presume food on a holodeck is real too.

On a related note, I always thought Sisko's objections to the Vic Fontaine program was odd and out of place. I never took it as a historically accurate depiction of 1960's Las Vegas, it's clearly modeled on an Ocean's 11 type movie fantasy Vegas. (The Sinatra one.) It's no more to be taken seriously than Bashir's spy program.
