Set the table with a green tablecloth, vases, and party ware. I like the cool flowery napkins shown here - they remind me of a stylized shamrock. Green spider mums in dried split peas is an easy but attractive centerpiece. Make an Irish flag banner with felt, fabric, or paper cut into triangles and hot glued to ribbon.
Serve a buffet of bite-sized foods consisting of traditional fish-n-chips, mini shepherd’s pies, and mini reuben sandwiches. Wash it down with a “Pot of Gold” cocktail with flecks of real gold from Goldschlager. Set up your cocktail bar with rainbow colored streamers hanging as a backdrop, and place a sign that reads, “A ‘Pot of Gold’ at the end of the Rainbow.” Have some glasses already filled and lined in rows. Scatter gold coins around the bar top and around the glasses.
For dessert and favors, set up a Sweets Table with candies, cupcakes, and green rice crispy treats, along with decorative take out boxes. Be sure to have Irish Coffee available too.
