Alcoholic beverage word association, quickly: "France?" Of course you said "Wine". Good beer is available in France, just not in the variety that an Oregon beer geek has come to demand, and not piled high in every restaurant, diner, and convenience store the way good wine is. After a week in the Loire Valley and Paris, I'm delirious with joy if a bar has Affligem Blond on tap instead of the ubiquitous and somewhat cloying Leffe Blonde; in the supermarket the best option tends to be Hoegaarden tall-boys, though I did drink a couple Kronenbourgs to support the local team.
The proprietor, Simon Thillou, is very welcoming, and gives personal attention to each customer that walks in, to try and guide them in their beer selection. I watched him work with an older couple who came in to look for a bottle to impress a beer loving friend: "Do you want something stronger or less so? Darker or lighter? Sweeter or drier? How bitter?" They were beer novices, and balked a little at "bitter". "But you drink coffee, you eat chocolate, don't you? It's not bitter in a bad way." He's equally adept at working with a picky beer geek, starting with a few questions about what you like, and branching out with some choices to help you explore the French beer scene. His English is probably better than your French, so don't hesitate to ask questions.
French Ninkasi in Lyon, which predates the Oregon one. La cave à bulles is open Tuesday through Saturday, 10 AM to 2 PM, and 4 PM to 8 PM (but not Wednesday mornings).
I only got to make one visit to the Cave à bulles, because the store is closed Sunday and Monday, we arrived in Paris in a downpour Saturday evening after it was closed, and we left town Wednesday morning before it opened. I'm glad I finally made it there, and I highly recommend it to you if you're visiting Paris.
