First of all, thanks for the enormous amounts of useful information I've read to plan my trip, coming up in a couple weeks.
I lived in Paris as a grad student, but now can afford a little more. I'll be taking my fiance and friends sightseeing near Notre Dame on a Monday, and was planning on picnicing that day for lunch. We're staying in the 5th and I'm planning on Eric Kayser for bread, but don't know what is open on Monday for cheese and charcuterie. Any suggestions?
Also, we have lunch reservations at Chez L'Ami Jean and Spring. We'll be sightseeing before and after. I plan on bringing a change of shoes, but is a jacket and/or tie necessary at these places for lunch? I've read mostly posts on dinner. Also, is a jacket/tie suggested for Les Papilles for dinner?
