Went to Northside Nathan's last weekend with my guy and our friends. We had fries, wings and a pepperoni pizza. I didn't eat the wings, but heard they were pretty good. Atmosphere was alright, nothing crazy. The fries were good, nice and crispy, and their ranch went really well with them. The pizza was decent, the crust had a nice garlic-y taste. The $40 total for fries, pizza, and wings seems a bit high to me, considering the quality.
Overall, I wasn't really wow-ed with Northside Nathan's. Would probably only come back if it were a friend's idea.
