I've been back several times since our first visit and I have to make some additional comments regarding the food. the hamburger is very good, but some of the fried food is just over fried and I would suggest you stick with the burger or one of the specials. The rest of my review stands.
Some friends asked us to join them at Jack's to enjoy some country music and so I proceeded to read the Yelp reviews and thought that I would get poor service, expensive and mediocre food.
Well, I was glad to see that some of the reviewers were out to lunch themselves. The service was great and attentive as my water glass was refilled several times and there was no wait for service. The 1/3# burgers we had were excellent and the fries more than I could eat and the price not more than you would pay at most sit down restaurants. Most items on the menu are less than $10 bucks so if you think that is expensive, better stick with Mickey D's.
Plan on going back this weekend for some inexpensive food and good music and cold beer. BTW the band (Seth Turner) was excellent.
