I would strongly suggest that if you go to Cacao 70 you REALLY like chocolate. There is barely anything on this menu that isn't chocolate, chocolate infused, or extremely sweet. The good thing is that I really like chocolate.
The service is really slow here so I hope that you aren't in a rush. It took about 10 minutes to get my coffee (iced) and in the end I had to send it back because my husband watched the guy make it. He used his FINGER to stir the coffee. The waiter understood and brought me a a new coffee and obviously at no charge.
I was trying to find something relativity healthy to eat for my daughter to no avail. We ended up getting her just strawberries. The food simply wasn't as amazing as I thought it would be based on the Urbanspoon ranking of "10 Top in Montreal", so maybe I went in with high expectations.
I would probably go back if I was having a chocolate fit.
