A Lava Flow is very similar to a Miami Vice, but they are actually different drinks. A Miami Vice is basically a Strawberry Daiquiri mixed with a Piña Colada, but separated in the glass for presentation. A Lava Flow doesn't include that lime juice, and instead traditionally adds banana (more on that later) - so really, a Lava Flow is kinda like a Banana Daiquiri mixed with a Piña Colada.
