I don't really understand the hype. It is not bad, but far from being good.
The things I did not like:
1- The croissant is very flaky but tasteless. Almost no butter taste and no salt.
2- The chocolate filling in the Oh Mon Dieu is kind of gelatinous, like a hard pudding. I did not like it all and I normally love anything with a decent quality chocolate.
3- The baguette is too dense for me. The crust is ok but the density of the inside is simply too chewy and heavy.
I really wanted to love this place. Oh well!
Might give it another try again in the future.
