I know the Sci-Fi gets bad reviews, by some, on these boards, but DW and I have eaten there, maybe 6 times. We enjoy the experience. We have found the service and food to be good. On our Feb. trip my sister and BIL had the chili at the Sci-Fi and they liked it very much. I had the ribs and thought they were good.
During our 28 stays at WDW I have found the food and service to be inconsistent, at most eating places. This might be the reason for different opinions, plus we all have different tastes.
