We checked out Tout Sweet on opening day. It is a cute space on the 3rd floor of Union Square Macy's. At 5:30 they were sold out of the small Tesla tarts. They have two gluten-free cakes - their Tout Sweet (chocolate and milk jam) and the La Vida Pura (pineapple coconut). We opted for the latter and 4 macarons (salted caramel, lavender, pasilla chili and chocolate and Meme - pistachio cognac cherry chocolate). They had plenty of other offerings - baked goods, pate de fruit, candies, marshmallows, cookies.
The space is fun and childish. It wasn't packed and service was perky - almost a bit too much.
We opted to take our goodies to go, which were lovingly overpacked in a large unwieldy cube bag. The goods all survived the trip back home.
The macarons had a delicate shell, with a bit less chew than I prefer. The flavors were also too subtle for me, except the pasilla chili which I thought was nice. I often feel people are going for the wow shock in chili chocolate and overdo the chili. The others just tasted sweet and I love macarons.
The caramelized pineapple in the cake was very good. Tender, sticky, sweet. The cake was very mild in it's coconut flavor and I think it had almond flour as it's primary flour. Overall the cake was good, but very unidimensional. I wanted a contrasting flavor.
Overall, I will probably return, but wasn't blown away. I honestly haven't tried a ton of french patisseries in the city. Probably better than say Cocola, but not as good as many I had in France.
