A Perfect Overall Margarita Experience rating would be a 40 . That's nearly impossible, given the numbers of people voting and their subjective experiences. But the closer to 40, the better the margarita experience. We compile all the reviews and arrive at the OME score by multiplying the Taste score by 2, and then adding the other 2 categories to this. Perhaps the venue overlooks the water, or a mariachi band plays to your table.
Service plays a role.
If the margaritas are wonderful, but your waiter can't be found to get one for you, this is often not fun, or pleasant. And you might not come back. The presentation of the drink is important. Salt probably should not ruin your drink, and the color should not be offensive. But that's up to you to decide.
