I have not been to the butcher, but I assume they sell the same products as Underground Meats since they're the same people.
I just have to say their Nduja (spreadable spicy salami) is a fantastic price compared to other places I shop and I love the taste. Less than half the price of some other places I see it for sale!
I have also tried their Ghost Pepperoni and it's awesome. I can't wait to make a pizza with it some day.
