I put on my glasses and looked it up.

RIVER CITY CASINO long ago.

According to this old newspaper entertainment review, one Dennis Lewis owned the Nashville West:

And you'll find some things on your favorite impresario, Lloyd Hhickey, too. Also, if you scroll down, a Pat Murphy, Iarry Freitas & Warren Sjothen Card Room, 5147 Madison Avenue. If huntin' is more your style, pardner, get yerself one of those 169“ Remington 870 Shotgun 2V Vent Rib Reg. 189.95. Watch the deer drop dead of laughter as you try to maneuver that 169-foot long barrel.

The second address of Nashville West, 6601 Watt Avenue in North Highlands, is now the Second Slavic Church. I'm guessing there had to be a building tear-down and rebuild up there.

PS: I'll save y'all some time on the 5147 Madison address - it was The Sticky Wicket, one of the entries on my Dark Side of the Moon Cardroom list - had a license but did not make it past 1999 or so. Address now seems to be a bunch of condos. You find a Sticky Wicket chip, I'd sure like to buy it!
