You're probably wondering how I managed to survive Paris when the euro was raping the dollar with no mercy. Here is your answer: Monoprix.
They stock this one generic brand of smoked salmon that costs 3 euros for like a pound and I used to have that as my day's food. It tastes better than premium brands, actually. Also, two words: coconut yogurt. I don't know why there isn't coconut flavored yogurt in the US, but I think it's simply unacceptable.
Their wine selection is also stellar if you are into buying wines for less than 5 euros, and who isn't? Even if you're on vacation, I highly recommend getting grocery for snacks and then only dining out at select spots. Especially if you're going to visit a spot like Sacre Coeur, the selection of eateries in the area are just an abyss of traps for money, you should definitely bring a picnic basket with you and eat on the steps and enjoy one of the best views in Paris. Seriously, I just shed a baby tear at the thought of it.
They also have cute lingerie and espadrilles [in the summer]. I love you, Monoprix. I didn't think I'd ever feel that way about a supermarket, but you changed all that.
