Coal Burger is a good solid burger. But it's not great, and the prices might set you up to expect a great burger. For two cheeseburgers (one 1/2 lb, one 1/4 lb, no bacon or anything), two drinks, and two orders of fries, we were at about $25. Now, the drinks are awesome: not only do they have only cane sugar in the fountain, but they have a Boylan soda fountain. Boylan makes some of my favorite sodas ever, so I was thrilled to see this. (Though saddened they didn't have cream soda.) I didn't even know Boylan offered fountains. Awesome.

The burger came out and it was good. Cooked the right level of medium, slathered in cheese, and fresh tasting. It's a solid, quality burger. But it's missing a bit in the way of flavoring or spice or pizzazz. Smashburger has a flavor to it that really brings it home. Chuckbox has a great mesquite whisper to it. Coal Burger didn't taste particularly much like anything special. I didn't get notes of coal/char. It was a completely serviceable, tasty burger, but it didn't blow me away, and for $12.50, I expected a bit more.

Now, that said, $12.50 is really only a couple bucks more than Five Guys and I didn't feel disgusting afterwards.

It's also worth noting that the sweet potato fries were some of the best I've ever had: crisp, but not burnt, and perfectly cooked. A good portion, but I could've used some aioli, and wasn't really looking to add 50 cent charges to try their sauces.

Overall, I'd probably give Coal Burger a 3.5, but the price and lack of HOLY BURGER impact left me at a 3.5. The sodas are an AWESOME treat, and the fries were perfect. Service was fast, friendly, and spot-on as well.
