Cookie Chaos
Little Z's is just off 110 east of Chelmsford Center. Outside picnic tables and window service, but also a couple of indoor seats and an indoor counter - and an opening in the wall that connects it to Zesty's Pizza (Little Z's is basically a seasonal spinoff.) It's also in the same building as Euphoria Coffee (which should really just add an Affogato to their offerings, especially if it involves sneaking out the back door to pick up the ice cream from Little Z's. ⛾ 🍨 ) Plenty of shared parking - and the Bruce Freeman Rail Trail runs along one edge of the parking lot, so there's also plenty of trail to walk off your ice cream, if you're into that.
The Little Z's menu includes ice cream, smoothies, soft serve, frappes, floats, smoothies, and raspberry lime rickeys; an interesting list of flavors and toppings (including twix pieces, toffee bits, and sour worms.) Their August Specials included a "Salted Caramel Pretzel Frappe" which seems like too many salts, though perhaps it's worth a try anyway.
First Visit
I had Grasshopper Pie (which was a refreshingly strong mint with crumbled chocolate cookies throughout - if you often find yourself thinking that mint chip ice cream is just Not Minty Enough, it's worth trying this instead) and also Cookie Chaos (which, as the name suggests, has a little bit of everything. Lots of crunch.)
I also got a taste of their strawberry - after trying their amazing mint so I was braced for not being able to taste anything else - but the strawberry shone through, I was pleasantly surprised.
Next Time
Next time I'll probably try the Pistachio and complain about the lack of Maple Walnut (though they do have walnuts as a topping, maybe mocha chip with walnuts and pretzels to get a similar texture.)
