This is more than just a croissant bakery. It's a rather charming French neighborhood cafe: the sort of place where you order some items and can then spend the entire afternoon if you like. I believe cmeckhardt told me she did just that a couple of times last summer, in fact. The temptation to order just one more coffee, hot chocolate, or pastry is often too great to resist. We couldn't. The management and staff are very nice about your lingering, even if they are busy, as they were this Sunday morning. In warm sunny weather the tables on the sidewalk terrace are particularly inviting.
The croissants are first-rate, of course, as are a number of similar pastries, and not particularly expensive. I had an open-faced breakfast sandwich special (croissant, egg, ham, cheese, tomato) served with coffee and orange juice for $7.95. bedfull_o_books and bercilakslady got croissants of various sorts, all for a couple of dollars each, and some fruit salad with yogurt and honey. Quiches, salads, and the like are also available.
In the evening they serve light dinners, with specials listed on a chalkboard, which also lists wine specials. I've never tried either because I've never managed to get there in the evenings.
They also have a selection of their croissants and pastries for take-out. Prices at the take-out counter are cheaper than eat-in prices, as is normal for a cafe.
