I tried this truck a couple of weeks ago during a night market event in the ID. It was a somewhat chaotic scene with many trucks*, and I had never heard of Nosh before, but the line 30-40 deep drew me in, and it turned out to be worth the wait. It's essentially modern/English bistro fare served from a truck.
Fish and chips was a huge slab of true cod served London-style on newsprint with good fries and an intensely mint-flavored, delicious portion of "mushy peas." My wife and I have been discussing how to recreate that one. The roasted bone marrow with crostini was a take on the famous Fergus Henderson dish, with a bone split lengthwise and pickled fennel added to a parsley salad. Rich and great. For the night the special was fried chunks of pork belly served over a Thai-style som tom which was hot, fishy and funky enough to shame the Lao specialists in town.
For all this plus a drink we paid less than $30, which is just not possible to do if one wants dishes of this quality in a bistro setting. Nosh represents a revolution in this sense alone.
* Also remarkable was an Indonesian truck called Tiga Dara/Bumbu Truck. I did not sample, but some peeps in the Nosh line had a plate and it looked and smelled intriguing.
