This, to me, is what makes the Mccaren airport a great layover. I don't know where else I can get Ethel M other than online and Vegas, so it's nice that they have it at the airport. Shipping can add up to these costly confections.
I love the chocolates and the samples I've tried, but of course yummy things come with a price. It's $2 a piece of a small chocolate. It's worth it if you are a chocholic or getting it for someone who is or at least to try once. I wouldn't buy a premade box. I would rather make my own, so I can get more of the things I like.
My faves are the pb&j and the sea salted caramel. Seems to me every time I visit that the workers aren't so welcoming though. Doesn't bother me much because it's a quick visit, but I can see them discouraging customers from getting anything.
