I had to look up Hi-Life Burgers. I don't think I have ever been there. The food looks good.
https://hilifeburgers.com/Tommy's is always a favorite. I used to go the original Tommy's in LA when I was in graduate school at USC. Tommy's actually bought all of our chemistry glassware (beakers, flasks, etc.) when our new chemistry building was built in the 1980's.
All of our glassware had the Tommy's logo silkscreened on them. I should have bought some while I had the chance.
Der Wienerschnitzel (only old guys remember the Der) is definitely a cut below Tommy's. Actually, a large chasm would better describe it. Their chili is like liquid and their hotdogs like rubber. Still, I eat there a lot.
As far as In n Out, well, that's what a hamburger's all about. Plus, contrary to ratings I find on the web, I really like their fries.
If you like good Mexican food, try El Tepeyac Cafe
https://www.eltepeyac.cafe/The Hollenbeck Burrito is a classic. Or you can get the giant Manuel Special.
Folks would line up in the rain to eat there.
There is now one in La Mirada, which is bigger, but lacks the experience. I discovered the new location recently and had some food delivered.
