Mythos is a must do for us, for the setting as much as the food. Same for Hard Rock. Bubba Gump is a must for me (not so much my family). Red Oven has become a staple for us. Great pizza and very inexpensive. Believe it or not, 2 counter service are on our must do's - Fast Food Boulevard in Springfield and Circus McGurkus in Seuss Landing. Better than average fast food both in great settings.
We did Toothsome and really enjoyed the food and service, not so much the desserts. But we'll do it again. NBC Sports Grille was a one and done for us. Nothing special at all and a very ho-hum atmosphere I could find at home.
