We usually end up at Backlot Express by default if doing QS, haven't found anything we're really thrilled for. Sometimes we go to Sci Fi, it's not that much more than a QS.
We usually do Backlot Express or just snack in DHS and not do a full QS meal. The only real reason for doing Backlot Express is because there is a lot of seating. Keep intending to try ABC Commissary once.
