Since money needed to be watched, there's not much we expats could do but buy some cheap wine, cheap baguettes, and maybe splurge a little for desserts.
Wine
Being no cook, I always brought the wine. A bottle of 3-5 wine was flavorful. That's the good thing about being in France--the sky's the limit when it comes to the number of good wines.
If you find yourself in Paris, try going to a Monoprix or Nicolas for the best-priced wines!
Baguettes
French bakeries are notorious for providing the best baked goods in all of the Western world (I'm not exaggerating a bit). These boulangeries are not skimpy on the bread; there's a wide array of breads, each delectable in their own right. I dare you to try them all.
A good traditional baguette will be no more than 1. If it's even a centime over, change bakeries. One of my favorite types of bread was a loaf of
pain au gruyre, basically gruyre cheese baked into bread.
Desserts
Boulangeries more often than not have great desserts to choose from. However, traditionally desserts are found in a patisserie, but now-a-days there's more combination of the bread and desserts in a single shop.
In France, you'll find probably the most impressive (and delicious) desserts in all the western world.
If you're around during Spring, get your hands on a sweet Galette Des Rois (King cake). They're large crusty cake-like dessert filled with fruits.
Let your eyes feast and let your mouth party with delicious food.
