One disclaimer on meal ratings I should disclose - I had my stiffest drinks of the trip at Raglan Road and Maya Grill. So that may have made the experience seem even better than it was.

Which really speaks well of Trails End, because it was morning and the only thing I had to drink was coffee.
That has to be it.
Having dined more times than I care to admit at Raglan Road, not once would it rate in my top 10.
It's a favorite of a traveling partner of mine so when I'm with that friend, we go. I've yet to have a meal I truly enjoyed there but hey, the things we do for friends.
I'm floored that you put Steakhouse 71 at a Denny's level. Maybe your Denny's are different than ours? Ours doesn't even serve things I'd call food. It's where drunks go to sober up. They have no business outside of that. Ever. Drunks never care what they are served. It just needs a lot of grease to absorb the alcohol. LOL Denny's has that, and then some.
T-Rex, well, Landry's food is never been on anyone's top anything list I don't think. Unless it's a top loudest dining establishment list, LOL.
We've gone to Steakhouse 71 several times and liked it. I find it isn't really different from The Wave, other than the name.
We gave Whispering Canyon another chance recently and now know why we only go there when a tour makes us. It's just poor barbeque. Granted, I'm from an area with excellent barbeque so that may have a lot to do with it.
I'm on the fence on Space 220. We've been 3, 4 times. Lounge only. Love the drinks. The food we've had is ok. Some great, some so-so. Thankfully it was never bad. The sliders were a saving grace though. They were enough to get us to return actually. Oh, and the deviled eggs. DH and I are sort of deviled egg aficionados and found theirs really good. I wish it was more hits and less so-so. We've never done the prix-fix menu.
