Vegetable Platter

• There are many ways to dress up a vegetable platter for a casino-themed birthday party. Stuff celery sticks with crab meat, parsley and cream cheese. Add pesto-stuffed cherry tomatoes, cheesy bacon-stuffed mushrooms and marinated green olives wrapped in provolone slices to the tray.
  
  Peel and slice 3-inch-long pieces of cucumber to create cucumber cups for the vegetable platter. Set the cucumber with the flat side down and scoop out two-thirds of the inside to create a cup shape. Fill the cup with diced red onions and chopped peanuts that have marinated in a little vinegar and sugar. Add the cucumber cups around the edges of the tray to create a frame around the gourmet vegetable platter.
  
  

Seafood Bites

• All-you-can-eat seafood buffets are a big draw for casinos and nearby hotels. Provide birthday party guests a small sampling from one of these buffets with an array of seafood finger foods. Fry cooked crab, onions, herbs, egg and breadcrumbs together to create crab cakes. Clean, cook, chill and serve shrimp with cocktail sauce for shrimp cocktails. You can also offer crab puffs, lobster puffs, spicy marinated shrimp or seared scallops skewers.
  
  

Finger Sandwiches

• Use cookie cutters and fancy ingredients to turn plain finger sandwiches into casino-themed snacks for a birthday party. Create heart-shaped finger sandwiches with rosemary bread, cucumber slices, red onion slices and cream cheese for a meat-free snack. Make diamond-shaped sandwiches with Parmesan-herb bread, thinly sliced prosciutto, shredded mozzarella, sliced tomatoes and pesto for a rich snack.
  
  

Mini Quiches

• Quiche is considered an indulgent dish consisting of egg, milk and cheese custard in a light pie crust. Mini quiches use pre-made crusts or dough and bake in muffin tins to keep the dish finger food size. Fill prepared shells with egg, milk, cheddar, spinach and crumbled bacon for a classic flavor. Mix egg, milk, feta, diced olives, diced onion and roasted garlic for Greek-inspired mini quiches.
  
  

Assorted Sweets

• Not only do little candies and treats offer birthday party guests a mini dessert, they are also versatile items that can easily become casino-themed snacks. Fill small treasure chests with foil-covered chocolate coins and gem-colored hard candies for guests to nibble on. Decorate round sugar cookies to look like poker chips, square sugar cookies to look like dice and brownies to look like playing cards.
