Pat a Chou has been in HCMC for a long time and the main draw are their baguettes, which is as good as the ones made in France. I had a ham and cheese sandwich and my partner had an almond croissant, both were excellent and hit the spot. We went back at another time to try their gorgeous looking desserts, we ordered mille feuille and moka cake (I forgot to take photos), but they fell short of expectations. I think the problem lies in the cream, they may have used shortening instead of real butter. The cream part just tastes thick and a bit greasy, and very sweet.
I'd say stick with the breads and pastries, have a coffee and enjoy an afternoon in their spacious, French-inspired shop.
