The one reason I go to this place is the Haystack burger. Absolutely fantastic. The burger is well seasoned and comes with cajun-spiced mayonnaise that is delicious. The fries that come with it are equally as good. I went at about 8 at night and the music from the bar was quite annoying, there isn't much in terms of ambiance, but it is certainly worth checking out just for the burger.
Edit: The last time I was there the burger was not nearly as good as usual. The kitchen forgot to put the fried onions on our burgers, and when we asked our waitress for them they were not warm and seemed like they had been sitting around all day. Be sure to ask for extra sauce - its the best part but they don't give you much normally.
