The kids and I made a recent discovery - Pow! Burger in nearby New Rochelle (211 Main St. for those of you scoring at home) has one of Westchester County's better burgers (as well as a healthy dose of Superhero comics love).
We've made two visits and the original Pow! burger (featuring red onion, lettuce, American cheese, and a 5-ounce patty) has not disappointed me either time. If you want a fried snack to accompany your burger, I would recommend the haystack onion rings (tossed in buttermilk and flour, according to the menu) over the house's fries, which I found to be mediocre.
