Last night Jennifer Lopez, mama Guadalupe, and hubby Marc Anthony were spotted at über-posh The Bank nightclub in Las Vegas. The couple sat in a luxe private table inside the club at the Bellagio Hotel and Casino.

No Cristal for this Hollywood couple! J.Lo sipped water and Marc sat back with a Coors Lite! Private tables at The Bank are not easy to come by -- a two bottle minimum is required and the cheapest bottle is $475.

An insider reports the fashionably fierce J.Lo requested food from FIX Restaurant & Bar. The actress ordered $25 Kobe sliders, $8 fries and the unlisted menu item -- a gooey grilled cheese.

The Bank does not have an open guest list. Your best bet is to talk to the concierge at a Las Vegas hotel for assistance. General admission is $30 for men -- women are free!

Before hitting up the Las Vegas club scene, the threesome attended a preview performance of Criss Angel's Cirque du Soleil show "Believe" at the Luxor. The show opens October 31 and tickets can set you back anywhere from $60 to $160.
