It's totally a matter of taste.
For me, I'll never return to Mama Melrose's. I ordered a seafood pasta dish and there was an entire squid in it. Not pieces of calamari, but an entire squid body. UGH!! Tony's is subpar, at best. I thought Cinderella's buffet breakfast @ the Castle was poor...and generally, I won't do more than a snack @ DHS.
Then there are places where I'll only eat certain meals at. Kona Cafe is a staple for me for lunch and dinner, but breakfast was gross. (I love Tonga Toast, but it doesn't love me, so I got a basic scrambled egg meal. Never again.)
My favorites include Liberty Tree, Kona Cafe, Japan and Canada.
