Went to Cafe Claude last night (Saturday). As other reviewers said, the place is not pretentious or stuffy - very comfortable and casual, but not loud, which makes for a great dinner atmosphere. The special mushroom soup was absolutely wonderful; the french onion soup was a bit thin (too much stock), but the flavor was still very well-balanced. The beet salad was very interesting, but my friend and I would have preferred a cheese that was less pungent for this salad. The flank steak was done right, with good flavor, but the coq au vin was completely drowned out by the sauce -- the potatoes, the chicken -- EVERYTHING was overwhelmed by the sauce -- very disappointing. I could barely finish the dish. The desserts were the worst offerings for the night -- the clafoutis was unacceptably dry, and the soft chocolate cake (moelleux) was also dry beyond repair. Sure, you have the creme anglaise, but my friend needed not just one, but TWO, servings of the creme to get through the dessert - and when you have to pour on so much of the creme, you end up losing the chocolate flavor anyway. We have never had trouble finishing desserts, but this was one of those rare occasions where we just had to push the plates away.
Most of the staff seemed friendly and warm, but the (seemingly) French waiter who served us was haughty. He definitely needs some attitude adjustment. Then again, we joked that he was simply bringing us a taste of authentic French attitudes.
In summary, it wasn't a horrible experience, and the prices (as mentioned by other people) were not outrageous either, but in all honesty, it was below my expectations, and it's probably not a place I would go out of my way to visit again.
Pros: Comfortable dining atmosphere
Cons: Entree, desserts, and service needs improvement
