Drinks on a Sunday night?

[frenchprof]

Having dinner at Firmin le Barbier (Eiffel/Pont d'Alma) next Sunday night and wondering if there are any good stops for an after dinner drink (wine or cocktails) on our way back to our hotel near the Bois de Boulogne?

Many thanks!

Café de l'Alma on the avenue Rapp/ rue de l'Université. It's the preferred watering hole for (affluent) locals.
