This is another one of those places that I sometimes get dragged to by friends. There's a location sort of close by (I wish there wasn't) and that's why we sometimes end up there.
I have to mention that firstly, I hate the decor. I'm not sure why, and I couldn't really tell you any exact reasons, I just really don't like it.
As far as the food goes, just stick to the burger, it's "okay". Also worth mentioning are the steaks. I find that the steaks are an insult to steak lovers, and anybody who calls Turtle Jack's a steakhouse should be hanged.
I'm not really opposed to chain restaurants like some people are. Some great ones exist; Ruth's Chris, the Keg. As long as a restaurant is enjoyable I don't care if it's standalone or a chain. On the other hand, I am opposed to turtle jacks.
