French fries/onion rings. "We don't sell fast food, we sell damn good food as fast as possible" is one of DGB's mottoes. The curly fries ($2.50), however, are pure fast food — frozen, preseasoned, and lacking any potato flavor. On the plus side, the fries are crisp and don't taste bad. Onion rings ($2.99) are a bit greasy but otherwise OK.
Bags of fresh Two Good Potatoes line one of the walls at CG, and they are turned into some of the best fries in the city ($2.75). Onion rings are similar to DGB's ($3.75; a larger portion than at DGB).
Edge: CG. Big advantage for the fries; onion rings are a draw.
Shakes. The chocolate shakes at both spots are thick and enjoyable. DGB's is $4.25; CG's is $4.50 (with an option of a malted shake for 50 cents more).
Edge: It's a draw. And BTW, neither shake compares to Shake Shack's.
Conclusion: I like both restaurants. DGB's burger is tasty, and the place is A-OK for hanging out and having a fun, affordable lunch — or spending happy hour after work. The bar scene is what distinguishes this DGB from many other burger places in town. CG will probably prove more appealing to burger purists, partly because there are many more choices and options of high-grade beef, and also because having great fries is incumbent to achieving an ideal burger combo.
