There are two ThirstyFrogs (on the 100 and 400 levels), featuring signature rum drinks, and the BlueIguana is on the 400 level featuring specialty tequila drinks. All three bars also feature Carnival's private label ThirstyFrog Red draft beer.
Of course the idea is that if you enjoy the sample, you'll enjoy the ships.
