If you’re unsure of how to order margaritas at bars and restaurants, here are some good things to mention to your server:  - If you want the rim salted or not. - If you want it blended with ice or served on the rocks (which means over ice). - Specify the tequila you want, like blanco tequila or reposado and if there is a specific brand you like. - If you want a "float" of Grand Marnier. - Let them know if you want it skinny.
