The Banana Rocket, a frozen banana coated in vegan chocolate, is basically a Bluth's Original Frozen Banana from "Arrested Development." Sure, there's always money in the banana stand, but the downside to 3 Potato 4 is that it's about the same size; indeed, it is small potatoes. There isn't so much as a stool or a window ledge to lean against, so you have to walk straight out with your cone of fries, through a neighborhood with nary a bench or a park. Dipping the fries requires either exceptional dexterity or a third hand, because you can't exactly place that cone on its side. If you don't work in the immediate vicinity, this is going to be very frustrating, especially in chilly weather.
But hey, they're opening another of Salem, Mass.-based mini-chain in Berkeley shortly. And in a city where mediocre $17 sandwiches are no longer universally considered an insane outrage, a tasty $5 cone of fries is a rocket to the moon.
