Mine is Big river Grille at the Boardwalk. DW and I had our worst meal and experience eating at WDW in the 10+ years we have gone. The place wasn't even half-full the time we went, but as slow as our service was you would have thought its was full. It took almost 10 minutes from when seated to finally get server to come over and at least take drink order. then at least another 10 to come back with drink and finally take order. what was odd is that she only had 2 other tables she was serving , but disappeared a number of times into the back but never came out with anything. when our food arrived she said if yoyu need anything just ask.well guess what she disappered and wife had to wait another 10 minutes to get another drink, nevermind glas had maybe a sip or 2 when she brought out meal. Anyways the food wasn't very good either to the point that only ate about half the meal. The funny thing is that the server then said anyone up for dessert? never mind the looks of near discust on both my wife and myself from eating half of a bad meal. becuase I was raised to be polite. I said NOT TONIGHT--never mind I was thinking if I ordered desert that night it probably wouldn't have been brought out that night! Anyways we got out of there as quick as possible after that, and will never return there! 
. I hate coffee so will give this a mis thanks for the warning.

Needless to say, the prime rib was cold, but the potatoe's were hot. 
I quickly ate, and boogied out of there, and they weren't even crowded. 
We were there for lunch and it was all we could do to find something we liked.
