My favorite food is a Burger. I like the old Umami Burger.
It's a shame they closed down. The Bay area would be nothing it.  
They still have it in LA. But they changed the menu. The old Umami Burger was so much better. 
The burger was so savory. Maybe the new veggie burger would satisfy you. Unless that's not your thing.
I haven't tried it yet. But I might enjoy it. I liked the different layers of flavor as well as the mushroom and the cheese crisp which I can't make at home.
It's supposed to taste like real meat. It looks promising. Ever tried their crispy chicken?
I haven't yet! But I like how diverse their menu is. I'll check it out next time I go. I also liked some of their specialty cocktails
Fingers crossed that you find a new favorite soon! I know we're talking alcohol, but have you ever given their milkshakes a try?
