Realize this is an older post, but as we just returned from Disney and ate at Sebastion's Bistro, because of a couple sources recommendations, decided to add my 2 cents! I totally agree with the above poster 100%. Had such high hopes and left so deflated that DH & I had just spent $100 (with tip) for what for the most part looked and tasted like leftover food.
Hubby did like the steak - or whatever it was, I had some baked chicken. It was all dark meat which I usually won't eat, but I was very hungry and was trying hard to like the food. The veggies looked overcooked on outside, but the carrots and sweet potato (?) wedge was hard on inside and inedible. The dessert was not as good as Ohanas, as I was told. In all, couldn't wait to leave there and will never return.
I usually love most food at Disney because I really enjoy eating, (also cooking at home) realizing it is subjective from person to person. I tried hard to at least taste most from the plate they brought, but I was longing for even a simple hamburger at this point.
Anyway, have 'never' said any of this about any food at Disney, or anywhere else actually, but will not be seeking Caribbean Beach Resort out any time soon.
(Got the ressie 'spur of the moment instant' so that should have told us something - very few people seated)
