In the eternal quest for a good burger in Cincinnati, I traveled just across the I-75 bridge from Cincinnati into Covingon, took the first exit, and turned right, leading me within a minute to Herb and Thelma's at 718 Pike Street http://dunes.cincinnati.com/dining/details.aspx?siteid=1&id=7668&lid=5191&cID=2
I had read comments on various websites indicating this was a little known hole in the wall joint for a great burger and a cold beer, and that this fellow churns out dozens of these great burgers every day. Indeed, googling led me to an old non-dining article in the Kentucky Post that confirms this: http://www.kypost.com/news/1999/hicks111299.html
This is a no frills, smokey, somewhat cramped local bar with a small grill just behind the bar. If there was a menu, I never saw one. The selection was very limited - one burger size, with only onions, pickle, mustard and catsup available as condiments, as well as good old american cheese. No fries, but bags of the local Husman's brand potato chips (plain, bbq, and sc&onion) were available. I sat at the bar, the only one ordering food, amongst a small crowd of people mostly smoking and/or quaffing bottled beers, and watched from no more than 4 feet away as my burger was added to the hot grill, sizzled among onions for a while (I had requested and was granted grilled onions), as well as my bun top. After the flip, he added the cheese, topped it with the onions, and then the bun top. Interesting - a bun first toasted then steamed in this fashion.
It was not a big burger, but was nicely thick, with good beefy drip on a very soft bun. I don't think this will make anyone's tastiest or biggest burger list, but then when I asked fo my check, Chip (the owner and cook of said burger,said "three twenty five." I couldn't believe it, so I said "are you kidding???", and he simply said "yep". So I will say this - this is my absolute favorite CHEAP burger in greater Cincinnati, hand down. To recap, that was 1.75 for the cheeseburger, and 3.25 with the chips and can of coke and a glass of ice. Sweet deal.
