2 things I always get because for gods sake, they are the best.
1.) Jack Daniels Chicken Strips as an appetizer because they are the best
2.) Jack Daniels Burger because it is the best burger I've ever had to date.
The burger is always moist and always cooked to my liking perfectly, every time! The burger has all the flavors you'd come to expect plus something more I cannot put my finger on! The thing that makes this burger though is the sauce, the buns, and the fries. Let's start with the Jack Daniels sauce. This sauce is the king of sauces, the sauciest sauce you've ever sauced. It's savory, yet a little sweet and is the perfect burger sauce. The only thing I do differently is I also put Jack Daniels Mayo on my burger (ask for it) and that's because in my opinion, a burger is not a burger without mayo (or a good aioli as it's just as creamy). Moving forward, the burger is the perfect size which is complemented by the perfect bun. A semi-sweet bun that is big enough for the burger and it's contents yet isn't too bready. Adds flavor but only a little as it lets the burger do the flavoring up. The veggies are usually fresh too which is good. Lastly , where they nail this and other places don't....is the fries. You get some darn tootin' good fries at TGI Fridays and let me tell you, good fries are important for a good burger. I usually dip my fries in my leftover Jack Daniels sauce or I order more because that sauce is freaking amazing awesome.
This is number 1 on my burger list and so far the only burger that has come close to it is Five Guys and Red Robin though they are still not the best.
If you've never had a Jack Daniels burger then you  need to get up right now after reading this....you know what? Stop reading this and just get up, get in your car and go have one because you will never truly be happy until you do.
