The really big mistake was using electricity for an outdoor kitchen grill when propane or charcoal were safer and taste better. I imagine their illegal there.
I doubt the grill ran on electricity. But, FWIW, some very high-end outdoor kitchens have refrigerators, ice makers, wine coolers, and kegerators and even flat screen TV’s, surround sound systems, lighting and ceiling fans if they are semi-covered.
I’ve never had anything like that, just a simple 4 burner with a side burner propane gas grill on the deck at my old house but I did buy a rotisserie attachment for it.
That ran on electricity, but I used a heavy-duty electrical outdoor rated extension cord to power it, plugged into the professionally installed, outdoor, weatherproof and grounded outlet that I had also plugged to in a string of outdoor lights that I hung on the umbrella of the patio table.
If you wanted a cold one, I either had a cooler with ice on the deck or you had to go through the patio door into the actual kitchen and the fridge.
