We are visiting Ruinart and looking for a quick lunch after our late AM tasting. Ww will visit Billecart-Salmon that afternoon and will not have time for a long lunch.
Any suggestions for a quick lunch in Reims?

Not personal but Michelin usually has good recommendations:

Denise, we will also visit Reims this spring. Can I ask how you are getting from Reims to Billecart-Salmon?

Are you driving? Maybe have lunch by Billecart-Salmon. There seems to be much more to pick from there. We went on a really bad snowy frozen icy day. We took a cab from hotel and they overcharged since they were the only mode of transportation that day. There was not much by that area. We walked very carefully over to St Remi and then walked back to the center where all the places to eat seemed to be. We were doing ok but first day after landing. I can't even remember what we ate. I know we drank. Ruinart was closed but Taittinger was opened and loved their caves.

This would not be a "quick" lunch, but it's really a great experience. After our tasting at Ruinart, we had lunch at Le Parc Restaurant Les Crayeres which is walking distance from Ruinart. It was a perfect combination.
