I have dined at Yachtsman many times and have found it to be one of the best steakhouse on the property, It does cost a little more but worth the extra for the experience. I liked it better than Ohanas.
I agree with goofy on Le-cellier, it just has nothing to offer for being a so called steakhouse, The newyork strip they serve is tough and taste like eating sand, >>>funny you should say that, cause i ordered the newyork strip and was HUGELY disappointed in it! definitely a tough piece of meat! LOL!!!! the bread stick's are hard a stale. Planet Hollywood serves a fantastic tasting Rib-eye. so tender you can cut it with a fork.
If you need a place to dine while in Epcot, try the Garden Grill in the lands, the meals there were great, almost like liberty tree in MK.
