First off, I have to say that this restaurant is beautiful and has a great atmosphere. My 14 year old daughter particularly loved it.
I'd give service 3.5 stars. It took us awhile to decide what we wanted and by the time it was our turn to order (you have to get in line to order) none of the items we wanted like the croffles or paninis were available. We rushed to order something else because by then, there was a long line of people behind us. I wished they'd put a sign at the beginning of the line just to say what they're out from the beginning. The cashier was also not super enthused to be there lol. He wasn't rude though.
I'd also give the food 3.5 stars. It seems like the people in our party who ordered sweet things like sweet crepes, were very happy with their meals. The people who ordered savory things (I ordered La Canadienne) were less. My crepe had undercooked flavorless potatoes. If the potatoes has been roasted longer and had a little seasoning, I'm sure it would have been a different experience.
Overall, I'd try this place again but I'd stick to something sweet as it seems it's what they do best!
