In a large pitcher, combine freshly squeezed orange juice, pineapple juice, and lime juice. Add in the orgeat syrup and simple syrup, then stir gently with a wooden spoon for 30 seconds until fully mixed.

Cover the pitcher with plastic wrap or a lid and place it in the refrigerator. Let it chill for at least one hour.

Fill each old-fashioned glass halfway with crushed ice.

Carefully pour the juice mixture over the crushed ice in each glass, filling them about three-quarters full.

Drizzle grenadine into each glass, pouring it gently down the side to create a layered effect.

Top each glass with a splash of club soda or sparkling water for extra effervescence.

Garnish each Non Alcoholic Mai Tai with a slice of orange, a maraschino cherry, and a sprig of fresh mint.
