Tried Columbia Harbor House for the first time (after 8 trips!) in June....had the Lighthouse Sandwich and enjoyed it very much. DS 14 had the fish and fries and DS 10 had the BLT salad and they liked their food too. (DH had a Lighthouse sandwich also and inhaled it...)
We've eaten at all the CS in MK over the years. They are all pretty good, it just depends on what you are looking for food-wise. IMHO, Pinnochio's menu has really declined...we stopped there before we settled on CHH, but the menu was very limited and it just didn't do it for us.
If you are looking for a larger meal (like with "real" food), Cosmic Ray's will be your best bet. They have the chicken and ribs there. The other CS places are more sandwiches, salads, pizza, burgers type of places.
