We didn't like the bison steak, rather gamey we thought. We also didn't like the dessert we had, which was really nothing more than a bigger-than-normal zebra dome. Definitely not worth $10. And, TDC Nala is right -- the wonderful berry cobler which was my favorite dessert for years, is now down to 1/4 its former size and costs $10!!!
For my money, the mushroom soup is, and always has been, great. The cedar plank salmon never disappoints (except price-wise, where Disney has run the price up to something like $39, with the same piece of fish being more like $27 at Shula's).
In any event, we have not had service issues, happily, but at this point, we think there are better signature restaurants. We would pick Jiko, CG, Citrico's and Narcoosee's before Artist Point.
