Food plays an important role in Like a Dragon: Infinite Wealth. It's Ichiban and his adventuring party's primary mode of healing, with different dishes restoring different amounts of HP and MP. Food typically comes from one of three sources: it's purchased as take-out from fast food windows and convenience stores, cooked up fresh at a bar, or ordered for table service at a restaurant. Of the three, restaurant food is the most varied, effective, and beneficial, as it comes with special bonuses. Particular combinations of courses, called Combo Meals, might provoke extra buffs or unique dialogue scenes with Ichiban's companions.
