I have a hard time reviewing Mon Delice as a "restaurant" -- they do make sandwiches, and you can get coffee or juice with your purchase, but this is a bakery, through and through. There are no tables or seating area, so I would only consider this as a place to get baked goods or sandwiches to carry.
That said, during my one week trip to New Smyrna, I stopped in at Mon Delice five times. The bakery was located just a few blocks from the condo we rented, so it made an easy breakfast stop. I always order the Almond croissants, and as usual, they were incredible. The croissant filling has just enough sweetness without overwhelming the flavor of the pastry. My sons enjoyed the plain croissants and the sausage rolls. I found the sausage rolls a little dry for my taste. I did have a custard eclair one afternoon and it was every bit as good as I remember. We also had a family brunch hosted by another family member that pretty much relied on Mon Delice as the source of all pastries. The pastries were gone in an instant. I did get to try a bit of a miniature quiche, and it was great as well. The crust was just flaky enough to crumble when you eat it, but hold together on your fork. I was also impressed that in a mini-quiche they were able to get the texture just right. I've seen too many miniature quiches that burn or dry out a bit. Mon Delice has it right.
I highly recommend Mon Delice as a one stop bakery for breakfast goods and sweets! I've been going here for many years and it is still excellent!
