You don't have to leave the pool to refresh your cup. We'll bring you tasty small plates and cool blended drinks so you can continue to relax in the sun for as long as you like. Light appetizers, salads and sandwiches, as well as kid's meals, can be found on our Cool Water Pool Bar . Our bar serves up refreshing libations and keeps the beer cold, no matter how hot it gets outside. Cool Water Pool Bar & Grill opens when the pool opens for the season during Wisconsin's warmer months, usually May into September.
