The bacon cheeseburger does have your lettuce and tomatoes and it's closer to a classic burger. I almost feel bad for the bacon here, because the flavor of the smoke dominates the burger. Still, if you eat it while it's hot, it's a treat.
I was less excited by the Santa Fe burger, which tops a burger with roasted chilies and pepperjack cheese and then smears on a “Southwest” sauce. There was a little bite to the burger, but not nearly enough to match up to the meat's flavor. And here I really would have liked the roughage of lettuce, onion and tomato, just to make it feel more complete.
The curly fries are awfully nice, though they need salting. The key — and this is for almost everything on the menu — eat it fast. This is food that does best when it's fresh. The trip back to my house, about 10 minutes away, tends to compromise things.
But if you're out and about and you don't mind paying a little more for your sandwich, Charcoal Oven really does make some tasty burgers. Not blow-you-away amazing, but like a good backyard grilled burger. And that's a flavor I enjoy.
