Marcel Vigneron, the most-hated bad boy in the history of reality cooking shows (or so we're told) just spent some time in the can for allegedly consuming a little too much ... of the good stuff.

If you know what we mean. We mean booze!

The runner-up on Season 2 of Top Chef was nabbed Saturday morning on suspicion of DUI off Highway 1 in Laguna Beach.

Marcel Vigneron was stopped for speeding, but after showing signs of intoxication he was given a blood test and taken into custody.

Bail was set at $2,500.
