we're traveling to paris this july for 3 weeks and i was wondering what some dirt cheap eating options are. we do plan on the occasional respectable french meal, but given our grad student budget, we're also looking for some meal options, aside from boulangerie specials, that are under 8 euros. i'm thinking something along the lines of student dining halls, church basement fundraisers, flunch-like cafeterias, etc. my husband eats copious amounts of food and so the picnic thing can only go so far with him. the last time we went, we ate a lot of falafel, banh mi, and crepes. what else is there?
