Why is Russian food so damn good (and underrated)?

I'm from Los Angeles and not Russian at all. I'm black and Vietnamese. But I had a Belarusian friend that hyped up Russian food to me, and the first time I tried it, I fell in love. I introduced my family to it too, and we all love it and go to our favorite Russian restaurant at least once a month. I just stuffed my face the other day with Borscht, pelmeni, some kind of sautéed potato and sausage thing (they called it Russian grandma style sausage and potatoes), Kotleti and grechka (my fav), herring and potatoes, assorted mushrooms pan fried with dill and butter, some kind of shredded cabbage and carrot pickle (SO GOOD OMG) and blintzes cake for dessert. Everything was and is always so delicious I'm surprised its not much more popular in the states! I wish I could post photos in here to show how delicious everything was!
