Stack'd is a great addition to the Oakland food scene and easily the best place to grab food in the immediate area. Similar to Burgatory in the ordering style with the option of solid build-your-own burgers which come with a side of satisfying fries, I have no complaints! On the days you're feeling "healthy," there's always the option of getting a filling salad with cajun chicken and fries (yes, in the salad) that make it perfect Pittsburgh and almost forget that you're depriving yourself of a burger.
It has plenty of seating (including outdoor in the summer) so you don't have to wait for long even on days where it's packed. And speaking of packed, it often is and in a good way! It's got a fun vibe and special deals depending on the day of the week, so always a good place to get dinner and catch up with friends!
