Haven't posted about this yet I don't think, and it's a shame not to have this info out there for those who are coming to visit our fair city (drop me a PM, we'll share a homebrew). Simon at Cave à Bulles is probably the
expert in European beer. From historical breweries that have been closed for 50 years to the newest brewery in Bruxelles, he pretty much knows it all, and is happy to share his experience to help you find the perfect beer based on your tastes.
The shop is located at 45 rue Quincampoix in the 4th arrondisment of Paris, near a bunch of great restaurants, shops and museums. He's Tuesday - Saturday between 10:00->14:00 and then 16:00->20:00.
And yes, he speaks English! Also Italian. And French.
Here's a very, very small sample of his selection:
more barrel-aged stuff
Some of the Cantillon available
And finally, some advertising from Brew Dog which I thought was hilarious.
