Like a true Clevelander I have been to B-Spot many times and various locations. One thing I can say is you truly receive the same product no matter where you are, but to me the product is just a little blah.
I have tried a few of the different burgers and the only one I really come back to is The Gobbler. It really isn't great, their turkey burgers are a little tough, but I keep coming back just because I like avocado and siracha mayo. After I eat it, I am not necessarily disappointed but I am also not satisfied. The best thing about B-Spot in my opinion is the pickle bar, I love jalapenos and all the different flavored pickles. I would probably be better off making a meal out of that and the french fries.
They do have a great atmosphere for a beer and a burger, so that is why you will find yourself coming back.
