These are not actual oysters but bison, bull or calf testicles deep-fried. Also, you can look for Colorado-styled pizza which is much thicker than a normal one. You can also find many restaurants that serve fresh seafood and lamb dishes. Bison meat is also quite popular when you are exploring different cities in Colorado.
