my friends and I visited a wireless BBQ restaurant in Seoul. This place was different from traditional Korean BBQ restaurants, where you typically see high flames and smoky grills. Instead, they used a new technology—wireless BBQ machines. Each seat at the table had a small wireless BBQ device, which connects via Bluetooth to the restaurant's main control system. The temperature automatically adjusts based on the type of food being cooked, so we didn’t need to worry about manual controls. Watching this tiny device emit a gentle heat, I could hardly believe this was the secret to grilling meat.
