Yep. Brewberry is the place I was trying to think of! It is located at
18 Rue du Port de Fer, 75005 (in the 5éme arrondissement).
It is not opened long, a couple of months maybe.
Another place I like is La Taverne de Cluny, 51 Rue de la Harpe, 75005 (near the Sorbonne) just south of the Seine. It has a solid (if small) beer selection at reasonable prices (reasonable for Paris, that is!).
