Tried it tonight and concur that its a fine addition to the Frederick roadfood map.
It is nice to see, generally, a move toward 'fast' bugers and fries at a higher quality; such as with five guys (though I agree five guys has seen better days). In this case, I wouldn't say it was the best burger I've ever had - a Shake Shack on the 270 corridor will end that argument. But it was pretty good. The fries were also good, though not particularly crispy in my case. A chocolate shake was delicious, thick and malty - a highlight that my daughter wouldn't share much of.
What was surprising was the overall subtlety (or lack of) flavor in the meat, cheese, bun and bacon. I suppose a recent Shake Shack visit had me hooked - where the meat was spiced in some way and served on a potato roll, making both very flavorful without any additional toppings. Here, there's a beef flavor to be sure - but a bacon cheeseburger didn't seem to have that balance of beef, bacon, cheese and bun flavors. The #19 with goat cheese and flavored mayo was quite flavorful - so it isn't the case with all toppings, just some of the basics.
So I'd also recommend and will return. I don't think I'd make a journey to find it though - at least not yet. For those travelling either on 15 north-south or 70 east-west, it is (as mentioned) a quick couple of blocks from the highway exit. The ordering is completed indoors at a counter, but there is no indoor seating and only 4 outdoor tables - bring your dashboard!!
