While the Meat Cellar is very good, I have another option for your consideration. The fabulous
Magic Lamp Inn. It's on Route 66 in Rancho Cucamonga, about a 15 minute drive from Pomona.
It opened in 1955, same year as Disneyland, and can be even more magical than Walt Disney's Magic Kingdom on weekends when the local sixty-something funsters invade the bar and the live band crashes into
Hang On Sloopy and everyone floods the dancefloor to Frug their hearts out. I'm not making that up, I've seen it with my own eyes. (Although I held back until I finished my drink and the band played something you could Twist to instead of the Frug or the Jerk. I have standards.)
But it also is an old school Route 66 Steakhouse, sort of swanky-meets-suburbia, with a sunken fire pit in the dining room, red leather banquettes, a relish plate delivered to the table as a welcome course, and flaming Cherries Jubilee prepared tableside for dessert. Be ready to eat giant slabs of Prime Rib and T-Bone steaks, no vegetarian options available except maybe a Caesar Salad, tossed tableside naturally.
A Monday evening will probably be very mellow, there will be no band in the bar, but if you like old school steaks with all the traditional fixin's, it's a fantastic gem on Route 66.
You can't miss it after sundown, because the sign still has a gas flame firing out of the neon magic lamp, for no good reason except to look cool to passing Chryslers and Cadillacs. It's been doing all this since 1955, pre-freeway, when Route 66 was the only road into town from the desert.

I'm sorry, were we supposed to be talking about a Splash Mountain reburbishment?
