Nick's has an old steakhouse feel, with dark row tables and warm, yellow lighting that permeates the whole establishment, giving it an authentic 70s look. The prices are reasonable and the steak is actually quite good. The pizza looked appetizing, but was far more bland than its appearance suggested.
The waitress we had seemed a little tired that day and it wasn't exactly busy, but she was at least attentive. Which sometimes is all you can ask for.
The bar side of the restaurant seemed to be a little more happening than the dining area with the hockey game on a bunch of screens. That part was packed with people. It's location (across the street from McMahon Stadium) makes it a great place to watch the football game or stop in after for a drink.
I would definitely go back to Nick's.
