The people watching in this lounge is superb! We played "what state are they from" here for about an hour. You see all types stumble in - and you have a view of the casino so you can watch all those poor bastards losing money at the expensive tables. The waitresses (sorry, no guys serving drinks here) were very polite and efficient - nothing seemed to rattle them. On one visit I received the wrong bill (it was clearly not mine, it was under $30) and I brought it to the server's attention. She was so appreciative (told me I'd earned good karma) that I suspect they put up with alot of shit there.
One night there was a piano player and a bassist playing - they were fun to watch. They'd just play along, chatting with people as they played! Isn't that sort of like walking and chewing gum (meaning not easy for the rest of us).
Anyway - drinks are expensive but it is Vegas and it is the Bellagio. I wouldn't expect anything else.
