I first saw Autour d'un Verre on David Lebovitz' blog, and I've been really curious about it ... but I didn't go until very, very recently. Unfortunately, it was near the end of my time in Paris and I only got to go once :'( The second time I went, it was closed.
So be warned: it opens for lunch at noon, and it does not appear to be open on weekends.
There's a formule (is it possible to order ... outside the formula? There weren't prices listed) for an entrée and plat for 15€. I usually go for plat-dessert, but since that wasn't an option, I shrugged and picked out an appetizer. I got the entrée du jour, which was a soupe aux poireaux (leek soup), and my brother got the gazpacho. Both were excellent, depending on your tastes, but I was in the mood for something mild and French and the leek soup perfectly fit that. It was really great - and the bread was also excellent for getting every last bit.
Unfortunately, I don't know exactly what I ordered for the plat (I mistakenly thought it was a fish) but it was something fermier (some sort of farm bird, I suppose) sitting on perfect mashed potatoes in a delicious sauce. It was AMAZING. I really, really enjoyed it. My brother got the chili con carne because he doesn't like fish, and that was surprisingly excellent and healthy-tasting.
Unfortunately, we had to rush off, and we were really full from our meal, so we didn't get dessert. :( They looked pretty good, though. We sat on the "terrace," which doesn't offer a great view because Rue de Trevise simply isn't that scenic, but it was nice anyway.
It's a very, very small restaurant, and I don't know how crowded it gets, but it's definitely not good for groups. read more
