Does Los Angeles have good food?

There's certainly a vast selection.

Los Angeles has fantastic food with a lot of options, though I would argue its food scene and role as a "food destination" is still relatively young and the best is yet to come.

The city has 24 Michellin starred restaurants, recently inching out Chicago with 22 (nowhere near New York's 76 or Tokyo's 230, but it is still in the top 12 worldwide).  It is also the second most diverse food scene in the United States behind New York with restaurants representing 61 different countries (ninth in the world). LA's Koreatown has the second largest number of Koreans outside of Seoul and therefore the best Korean BBQ spots in the country. 

Some of the best restaurants with cuisines I haven't found outside of LA are a Burmese place not far from Disneyland called Irrawaddy Taste and a great Cambodian place called Monorom in Long Beach. The Los Angeles sushi scene is well known for its salmon, and I have had many an interesting conversation in Japan with sushi chefs about how great LA salmon sushi is but how its tuna pales in comparison to Japanese sushi. 

The only problem is that as of the time this post was made, LA restaurants are shut down for everything but take out.  That kind of defeats a lot of the experience. 

if you go to the right spots

Yes, there are lots of places in Los Angeles with good food.

Yes but right now you either have to order it for pickup or delivery. 

P.S. Pineapple pizza was invented by a Greek immigrant, Mr. Panopoulos, for his restaurant in Chatham, Ontario, Canada. So you could call it Greek or Canadian but it's definitely not from L.A. 

Twenty miles in any direction and you can travel around the world in restaurants. Seafood, barbecue, steamed, baked, boiled, and fried. Omnivore, carnivore, vegetarian, vegan and raw vegan, juice bars, water bars and even oxygen bars. Name it, if it isn't there, get a business loan and open one up and make a fortune. Pineapple pizza started there, now it's everywhere. Famous Amos cookies started in a shop smaller than the dining area in a typical McDonald's.
