I was not impressed at all with Mon Berri. A friend and I got a few different toppings on our Froyo Crepe, and the toppings were stale. The staff member looked like he didn't want to be there, and seem disappointed that he actually had to serve us while he was on his blackberry.
The froyo overall was a 5/10 but I could be a little biased because of the service, or because Menchies was a 5 minute walk away and the flavors are delicious and toppings are plentiful AND fresh.
