I have to say I'm extremely biased here because this place is just down the street with me. But come on, the owners speak French! Their pastries are incredible. Every time I go I get a few classic eclairs as well as a few more things that I'm unfamiliar with, just for fun. Not once have I ever had something I did not like.
I honestly can't think of anything bad to say about La Gourmandine. It's delicious and everything they make is done that morning. When they're out, they're out, and it's reassuring to go into their bakery right before closing and see that most of the stuff has been snapped up.
Their baguette sandwiches and quiches are also great for breakfast, brunch, or lunch.
I hope some day they get a nice espresso machine and put the cherry on top of an already near perfect establishment. If I can get my eclair with a foamy cafe au lait, I'd be in heaven.
