I am a safe eater. I usually don't stray too much from chicken or steak even at the more "exotic" places at WDW. It's hard to mess up chicken or steak and if you do, it's more about how long it was cooked at not the spices used-at least for me. Occasionally i will try something different. At CA Grill, they have a great pork tenderloin....
You sound like me, I'm always afraid to try something new or out of my comfort zone of what I usually eat. Well, the truth is I like to try things, I'm just concerned I'll end up with a plate of something I won't like. Buffets are great for this, there's bound to be at least one thing I will like.
I wish DHS had better Counter Service Restaurants.
