BT's has a few good things going for it. If you are a control freak who likes burgers, you should enjoy this place. You can build your burger from the ground up to your exact specifications. I will also give this place credit for being on the sweet potato fry bandwagon before they were available at a lot of places. The same can be said with the fried pickles. The burgers themselves are actually really good and of a much better quality than places like Five Guys. For a while, this was my favorite place for burgers. It is still on my list as far as the burgers go.
There are a few not so great things that keep me from going to this place more often than I do. The service, as you can see in lots of other reviews, is somewhat suspect. There is also the cleanliness issue. I think that the staff is pretty laid back in general and this probably doesn't reflect well on the place where you can see everyone who works there as you are waiting for your food. Additionally, I like a place with some character and this one really doesn't have much. It is kind of a surfer theme but it is kind of bland and just doesn't really do much for me.
I recommend this place if you want a good burger that beats the other chain stuff.
