A condiment bar for cocktails is a designated area or setup where various garnishes, mixers, and flavor enhancers are displayed for use in cocktail preparation. It serves as a self-service station or a resource for bartenders to customize and enhance drinks according to personal preferences or specific recipes. 
Typically, a condiment bar includes a variety of fresh fruits such as lemons, limes, oranges, cherries, and berries, which are used for garnishing or adding a citrusy or sweet note to cocktails. It may also feature herbs like mint, basil, and rosemary, which provide aromatic and flavorful accents. 
In addition to fresh ingredients, a condiment bar often contains a selection of syrups, such as simple syrup, grenadine, or flavored syrups like vanilla or almond, to add sweetness and complexity. Bitters, which are concentrated flavor extracts, are also common, offering a way to introduce depth and balance to cocktails.
Spices and salts, such as cinnamon sticks, nutmeg, or flavored salts, are available for rimming glasses or adding a hint of spice. Olives, pickles, and cocktail onions might be included for savory cocktails like martinis or Bloody Marys.
The setup may also include various mixers like tonic water, soda, or ginger beer, allowing for the creation of a wide range of cocktails. Tools such as muddlers, zesters, and peelers are typically provided to assist in the preparation and presentation of drinks.
Overall, a condiment bar for cocktails enhances the drinking experience by offering a diverse array of ingredients that allow for creativity and personalization, catering to different tastes and preferences.
