Came here on a Saturday around lunch for a light lunch. We ordered the prosciutto sandwich - with arugula, onion confit and cheese (I believe this was around $7-8). It came pressed and was prepared to order. There were thick slices of prosciutto in it, and the combination of it with the onion confit and cheese was to die for. A fantastic sandwich - highly recommended!
We also ordered a pain au chocolat, which was extremely disappointing. It was stale and not at all buttery/flakey. My boyfriend said it must've been an off-day since he's had them before and they're normally a lot better. Maybe I'll give this another shot next time.
They have a large display of pastries and desserts, which looked really good! Last time I was here, I tried the apple tart, which was really nice. We also had the capuccino eclair which was just decent.
Overall, Patachou is pretty solid - minus the stale pain au chocolat I had!
