Jean-Marc has the BEST cake and pastries in all of Pittsburgh (if not the state and/or country). Seriously, how can you go wrong with someone who uses such fresh ingredients? I don't even like chocolate cake with white icing - but I love Jean-Marc's half and half cake! I also am obsessed with the raspberry filling... yum for fresh raspberries! The icing is just out of this world. The pastries are also delicious. I love the salted caramel macarons... so good. And the original reason that we found him (in the 90s) was because my grandmother (who was born in France) wanted to try his croissant, which are also delicious.
He can also be helpful in a pinch. I forgot to place an order for my mom's birthday cake until really late. But he helped me out and was very nice about it (but always be nice in return, because he doesn't take any crap! good for him!).
We had our wedding out of state, and the only thing that I was disappointed about was the fact that we wouldn't be able to have Jean-Marc's cake for our wedding!
