Thanks for your questions “What are some of the most overrated restaurants in Los Angeles?” I think this questions restaurants in Los Angeles is very important for all like yours.
Here I’m trying to give your answers in brief.

I’m sure people are going to disagree with some of my answers:

Nobu: Super-expensive “sushi” and paper-thin sashimi, most of it swimming in ponzu so you can’t taste the fish. Twice I’ve eaten at Nobu and both times the waiter had no idea what I was ordering when I used the real names for sushi like “ika nigiri with shiso” or “hamachi sashimi”. The decor was nice, but it’s all hat and no cowboy.

Pizzeria Mozza: I ate lunch here once. There was a crowd and without reservations, we had to sit at the bar. All that led me to believe it would be spectacular food. I had an $18 personal-sized clam pizza and a $5 bottle of water. The clams were sparse and gritty/sandy and half of the pizza was the crust. The crust and sauce weren’t anything special.

Sushi Nozawa: I tried this parent of Sugarfish after falling in love with Sugarfish’s exceptional quality sushi and sashimi. Completely pretentious, way over priced, and not as good as Sugarfish. I suppose any place that lives on the reputation of how arrogant the owner is shouldn’t be expected to offer a great experience, but I thought the food would be even better than Sugarfish. Instead, it was more expensive, lower quality, and came with attitude.

Salt’s Cure: This place centers on meats and has a great story, but (according to all my meat-foodie friends and wife) the meats, while some are interesting, are mostly mediocre and the price for the portion size isn’t worth it. My wife had a $17 bacon burger for lunch (which she said was just ok) and IIRC the only beverage options were wines. A reviewer on yelp remarks the place smacks of “be seen” inside…which seems accurate.

The Ivy: If you want to see or are a celebrity that wants attention you eat here. You don’t eat here for the food, which is very expensive and equally unimpressive.

Gladstones: Location Location Location. Right on the beach with great views. There’s a reason the other location they tried failed. I think people in LA and even the owners generally accept that the food is overpriced and terrible, but it’s one of the few restaurants right on the beach.
