Manhattan Espresso Cafe was around the corner from my previous job, and they sold all sorts of secondary market deliciousnesses. My current go-to is Treehaus. Aside from baked goods and other great things, they sell chocolates by Nunu, Mast, and Tumbador:
I bought some Nunu chocolate-covered graham crackers. They were good. As described. They didn't blow me away.
From Mast, I bought a black truffle sea salt bar. Like with Nunu, I thought it was very good, but I didn't really get the hype. Everyone with whom I shared it, though, did get the hype. It was a bit salty and fruity for me.
Surprisingly, the winner for me was the Tumbador Mint Crunch, with nibs. This is obvious, because I ate it too quickly to get a picture of the bar itself. Readers will know Leila and my fondness for mint and nibs, so this might not be surprising. It might not be the best mint bar in NYC, but it's yet another darn good version.
Bottom Line: This isn't even scratching the surface of Treehaus' sweet offerings, to say nothing of their savories.
