Just keep in mind that it's closed in the summer and it is terrible from anywhere but the store. I want to say it closes July and August and a couple of days during the week but it's been a while since I have been. But if you go in that time, don't bother with the places that sell "Berthillon". It's not worth the money at all. I am sure there are other places in Paris that are a fraction of the price that are just as good or better. Going to the store when it's open is worth the cost, imo, unless youre on a really strict budget.
