Here's their menu from June, 2017 ...
https://piccolomarket.weebly.com/menu.html .... just my guess, was too up-scale, too high quality, too expensive .... not enough local customers especially through the winter months to keep it going ..... this area is more about chomping down a $4.50 Sam's frozen 4-cheese pizza from you know where .... wally-world ...aka Walmart .... which, by the way, does not get hit with the 9% prepared NH food tax because it is frozen.
Most everyone probably thinks long and hard about that 9% tax before going to a restaurant ...... don't you? So, by warming up a frozen pizza, you get to cut pizza, and cut taxes with each slice ...... ho-buoy ..... is making me hungry!
So, what's the last line at the bottom of the Piccolo menu?
"* Tax is NOT included in the above prices."
