Paula's Cafe is located in downtown Cincinnati. It has a sign outside that says Best Burger Downtown. I am sure they aren't the only place that has the same sign, but I now agree with their sign. Now I am JUST counting places actually downtown. I do not think is the best burger I have ever eaten, but I do believe that it is the best burger that I can get during my lunch downtown without having to get in my car and drive anywhere.
They call it the "7 minute burger". They call it this because that is how long it is on the grill for to make it how the cook wants to, which I believe is Medium. It is $6.95 for the burger and chips, to upgrade to fries it is $1.75 more. For cheese, caramelized onions or mushroom sauce it is $.50. And finally for $.95 more you can get an egg or bacon on top of it. I have had the burger now 4 or 5 times. I have it different each time. My last time I had it with just cheese and an egg, the first time I had it with cheese, onions and pickles. No matter the combination the burger has been delicious each time. I would recommend springing for the fries unless you like the traditional plain ruffle potato chip. Expect to pay close to $10 for everything and go all out for the best built burger you can think of. I don't go here much, but when I do I want to like it a special experience.
Usually when I leave (and sometimes even when I don't eat here) I grab a piece of their homemade carrot cake for my wife. She LOVES carrot cake and after she had theirs the first time (and every time since) she has said it is the best she has had (in Cincinnati). I have had their homemade brownies and they weren't the best, but usually I am too stuffed for dessert anyway.
If you haven't been here before, it is worth checking out. It is on 4th street in between Vine and Walnut.
