We've been interested in trying Jack's for a while now. The Yelp reviews were mixed and our experience reflected that same mix with some good and some just average to below. The atmosphere is like a darker version of most sports bars with lots of TVs all around. The food ranged from not bad - Wedge salad with what appeared to be housemade blue cheese dressing - my wife's blackened fish tacos to below average - my cuban sandwich and the clearly frozen, out of a bag onion rings on the side.
Seems to be a hangout for an older crowd (I can say that as I'm part of that crowd). All in all, I might come back sometime to watch a football game or something but Jack's won't be on our regular rotation of LKN stops.
