General impression: this is basically the Mecca of Sausage. It's notionally a general-purpose deli, with cheese and coffee and stuff, but mostly it's about the sausage, which appears to be entirely made in-store. And the variety is startling: not only do they have all the usual forms of sausage, they have a *wide* variety that I've never even heard of before, along with some that I suspect they made up. (I am deeply curious about the Porcini Sausage.)
And yes, they have 'nduja. (Whose apostrophe I have moved in deference to the apparent online consensus of where it belongs.) They were happy to give me a taste; my general reaction is that it's yummy. I don't think it's quite as richly-flavored as what I had in Italy, but I don't have a fair comparison -- the Italian stuff was melted onto pizza, whereas this was straight and uncut, and still fridge-temp. Tasty and properly deadly; once I have my grill unpacked for the season, I may need to try making my own pizza with the stuff.
Anyway, check out the store. I'm looking forward to trying out this and many other varieties of sausage there, and it seems like a place that deserves to succeed...
