I really like hell's kitchen show. although it's a bit hard, but that's how education becomes a chef
Time ago, some old participants of the Spanish version began battling in court against the show producers and presenter Alberto Chicote.
The restaurants owners claimed to have been verbally abused and treated like slaves as filming sessions lasted for up to 18 hours most days. Furthermore, they remark that during that time they don't actually trade and so they lose huge amounts of revenues.
Seems like the show does anything but helping the eateries to stay afloat.
