1 person each lounge. The dining car chief pitched into help occasionally. The servers likewise. Personally, I think at least one of those lounges could have used a second person during meal service. But still, it worked well enough and from a customer POV much better than Amtrak. I realize this wouldn't work precisely on Amtrak the way it does for VIA because Amtrak doesn't have the lounges configured (or enough of them) to mirror the VIA setup. I think the larger point is that GOOD catered food, handled efficiently on board, is something Amtrak should be looking at. BTW, the diner had decent dishes, silverware, tablecloths.
