Reggie Bush -- INSANE WEDDING MENU ... Drunk Food Included!

No wonder Reggie Bush's wedding is costing a fortune -- the NFL star is going ALL OUT for his guests ... loading up an insane menu that includes TONS of shellfish, booze and late-night DRUNK FOOD!!

Let's start with the shellfish ... because Reggie and Lilit will be offering their guests the following:

-- Shrimp with cilantro and cotija
-- Shrimp potstickers
-- Lobster and butternut squash bisque
-- Roasted jumbo prawn with mini crab cake and lobster sauce
-- Mozzarella and crab crusted beef tenderloin

As for the booze ... it's all top shelf stuff -- with Belvedere, Grey Goose, Patron, Ciroq ... and a variety of decent whiskeys including Johnny Walker Black, Crown Royal, Jack Daniels and Glenlivet.

But the best part of the whole wedding ... Mr. and Mrs. Bush are opening up a SLIDER STATION for drunk revelers to munch on between midnight and 2AM ... french fries included.
