If I had more money to spend on dining out I would be a lot more adventurous, but as it is I only try really new things every once in a while when the mood strikes me. Usually when I go out I want to know that it is going to be good.
My basic rule is I'll try anything once, there isn't anything I haven't tried that I haven't had the opportunity to try. Lately I haven't had the money for restaurants that serve some of the less typical stuff. For example, this summer I had medium rare kangaroo steak that was really good.
I'm not really into trying new foods. At a certain time in my life, I was forced to try foods that would support my survival, should I be lost in the desert or jungle...Ew. I have a sophisticated palate, but, stick with variations of a few basic things.
