D'Arcy's Pint:
The thing about the D'Arcy's shoe is that it is really better than the sum of its parts (except for the white cheese sauce, which is just incredibly delicious). This was clearly the best of the first three horseshoes we pitted in our head-to-head horseshoe tasteoff. It's the current "buzz" horseshoe around Springfield, and it certainly lives up to its reputation. It is the clear winner of the first tasteoff.
The Sauce:
The first thing I always notice on a horseshoe is the sauce. No matter what you love about a horseshoe, the first thing you taste is the sauce, which manages to ooze and puddle its way into every bite. The D'Arcy's white sauce is a definite crowd pleaser. It's tangy and rich, and it complements the fries and burger quite nicely. The only complaint I have with the sauce (and this is a common complaint with cheese sauces) is that you'd better eat it quickly or the cheese sauce becomes waxy and hard. The shoe we ate on the show had been sitting for almost an hour, and it was almost completely inedible. As you can see if you saw the show, we had a heck of a time eating it.
The Burger:
The burger on the D'Arcy's shoe was the biggest of the three burgers we sampled. It was clearly bigger than the Thirsty's burger, but it was embarrassingly bigger than the Dublin burger. We all commented on the size difference between the D'Arcy's burger and the Dublin burger. It was striking. The thing I like about the D'Arcy's burger is that, flavorwise, it blends very nicely with the other flavors of the horseshoe. It doesn't really stand on its own. It just provides a rich, meaty undercurrent that complement the fries and cheese very nicely. It's not greasy, and it's not dry (although it was cooked a little more than I would prefer).
The Fries:
I've never been a huge crinkle-cut fry fan, but D'Arcy's pulls the crinkle cuts off by making them blend well with everything else. As mentioned previously, the components of the D'Arcy's shoe all work well together, and each ingredient enhances the other two ingredients. These fries are especially good when they're fresh. I love a fry with some crispness to it.
Thirsty's Playground: 
The Thirsty's horseshoe was the surprise of the night. As we compared the D'Arcy's horseshoe directly against the Dublin shoe, we realized that the two horseshoes seem very similar until compared directly. As we had them right there together in front of us, there was a clear difference. Somewhere in that vast difference, the Thirsty's shoe slipped right in. This horseshoe was great, and I'd recommend it to anyone.
The Sauce:
The sauce was tasty, and I really like the richness, but it was nowhere near the D'Arcy's sauce. Here's one nice bonus to the sauce. When you carry the horseshoe out at Thirsty's, they give you the sauce on the side. You can go home, warm up the sauce and add it to your horseshoe. I really appreciated Thirsty's attempt to avoid sending you home with a waxy crapfest. The cheese was very tasty, and although it was "fresher" than D'Arcy's sauce, it just didn't hold up as well to the flavor of the famous D'Arcy's sauce.
The Burger:
Thirsty's burger is delicious. It was the only restaurant that asked us how we wanted our burger cooked, which showed me that they're customizing their horseshoe a bit more than just mass-cranking burgers and covering them with fries and cheese. Also, the Thirsty's burger is marinated, so it's nice and juicy. It has a delicious flavor, but it doesn't tend to meld as well with the other flavors in the shoe. It's a burger that would stand quite well on it's own, but it's too bossy to play well with fries and cheese sauce.
The Fries:
If we were voting simply on fries, Thirsty's would've taken the prize for me. They were homemade potato slices, and they were well seasoned. As I mentioned earlier, I'm not a huge crinkle cut fan, so I was pleased to see these fries. They were well-seasoned, and fresh. Very tasty fries.
Dublin Pub: 
The Dublin Pub was a disappointment to me. After D'Arcy's got so popular that it takes an act of God to get seated, I started using Dublin for my horseshoe fix. You can always get in in a timely manner, and their carryout is pretty quick, too. I've always been more than happy with the Dublin, and I felt it was very close to the D'Arcy's shoe. When we compared them head-to-head, though, I could really see why Dublin is considered the
other D'Arcy's.
The Sauce:
The Dublin sauce is great. It's almost dead-on the same as the D'Arcy's sauce. There's really little else to say than that. And if you're the kind of person who only cares about sauce, you'll see little difference in the two shoes.
The Burger:
The Dublin burger was not very appetizing. It was small, and it had little flavor. I was actually amazed at how small it was when comparing it to the other two shoes. Not that size is
all that matters, but a little more burger wouldn't have hurt us. But really the size taken with the taste (or lack of) bumped the Dublin shoe down for us.
The Fries:
The fries were not that unsimilar to the fries at D'Arcy's, but they just weren't quite as good. This was pretty surprising to all of us, because they looked pretty similar, but they lacked flavor and crispness. They were a bit soggy.
