I really liked the cooking-related quests in The Ruby Feast! Having just completed the achievement “Great Gourmand of the Ruby Feast”, I hope Blizzard can add more quests in the near future. They are fun culinary quests. Maybe future ones can add additional recipes as quest rewards as well! The food buffs are fun too.
I know some people had problems with finding quests or bug reports, but those are often because they haven’t finished the quest lines.
