This is a Burger joint that opened up herein Oakland on Grand Ave not too long ago.
I can say if you like In-n-Out you'll love these. They are only open for lunch Monday, Tuesday and Wednesday but open later Thursday, Friday and Saturday. Closed Sundays!
I do recommend checking them out and you will find yourself going back.
It can be a bit busy and crowded inside during lunch but you can also order to go.
