Having been to Bouchon Bakery in Yountville, I was slightly disappointed in the selection at this location. It is a decent selection and they do have specials, but they don't carry items like the chocolate covered macaroons. The larger macaroons also aren't as large as the macaroons I've had from Bouchon in Yountville (although the price is still the same).
They have a special where you can buy 5 macaroons and get 1 free. You can choose your flavors or they have some pre-packaged. The macaroons themselves, although not as big as I'm used to, are still really delicious...even a couple days after they're good!
Now that I know where this location is in Vegas (it's by the theater in the Venetian), I will definitely make sure to stop in for a treat. It wasn't busy at all either when we stopped in the afternoon on a weekday.
