Miami Heat -- 200 Bottles of Champagne Popped After Big Win

If you can't find a good bottle of champagne in Miami today ... it's because the Heat drank them all.

In the mayhem following last night's NBA Championship-clinching win, TMZ has learned LeBron James and company guzzled more than 200 bottles of bubbly in celebration.

We're told the team emptied 100 rare magnum bottles of Moët Ice Impérial champagne during the locker room celebration ... and then another 100 bottles of Dom Pérignon at STORY nightclub.

As for the food .... we're told Prime 112 (one of the best restaurants in Miami) sent over a ton of free eats -- Kobe sliders (oh, the irony), chicken and waffles, shrimp cocktails, and fried shrimp.

It's good to be the champs.
