What's making you curious about this - are you thinking about switching yourself, or just wondering if the hype is real? It's definitely happening, but here's what people aren't talking about: the big bottleneck isn't whether induction cooks well (it does), it's the upfront infrastructure cost. You need to rewire the whole kitchen for the power load, which can run tens of thousands of dollars, and most restaurant owners would rather wait out their gas equipment's lifespan than drop that kind of money now.
The building code angle that others mentioned is real, but there's a practical middle ground working better than people expect - hybrid setups where you keep gas for certain stations (like wok work, which genuinely struggles on induction) and go electric for everything else. It lets chefs keep their technique without a total overhaul, and it's way cheaper than a full conversion. The restaurants actually making this work aren't ditching gas entirely; they're just using less of it.
