The Buffalo Wild Wings Primo Margarita is made with Patron Silver Tequila and Cointreau. I was ready to be disappointed in a chain restaurant margarita after my experiences with Old Chicago.... but I was pleasantly surprised! This didn't taste like a pre-made mix, it didn't taste like candy, and it didn't taste like a non-margarita which made me love it! This was nicely tart and you could taste the tequila without it being over-powering. The difference between the Primo and the House margarita, other than $1, is the house was made with Sauza Gold, triple sec, and lime juice. In my opinion, if you are going to have a margarita, have one that tastes good! Don't worry about an extra $1 for the drink.... you'll miss out on some great margaritas that way.
