I went to the bakery late Saturday afternoon. They had beautiful looking mini pastries/cakes behind the counter, and there were some macaroons left. I would definitely go earlier in the day next time. I'd love to see what else is available if you go in the morning.
I ordered a bunch of macarons and the Breton Cake. The macarons are amazing. Each one had a great flavor, and the shell was light and crispy. They were the best I've ever had. It was my first time trying the breton cake. It was the most flavorful shortbread type cake I've ever had.
This is a must stop shop when you're in Pittsburgh.
