How do you open a bottle of Herradura Tequila?

It sounds like an anti refill thing inserted into the top of the neck of the bottle. You should be able to pour the contents out through it?

If it's not - ask the shop where you bought it - or go to the Herradura website, send them an email and they should be able to tell you!!!

Patron silver is a good tequila. But in my opinion the Patron Gold Anejo is even better! Its alot smoother not as much bite! It does cost more because its a Anejo 100% De Agave Tequila though. If your friend likes silver he will love the Gold Anejo! You can get it the cheapest at Costco! Its the biggest bottle for the price!!! Its a 1.75 L and I got mine for under $100. I can't remember the proof on the silver but the Gold is 80 proof. Its not cheap at all but its worth it! You can find smaller bottles at other places but costco is the best buy of the Gold that I have ever been able to find! Your a good friend!!! =)

Not sure what plastic thing you're talking about. I drink Herradura tequila - it makes the best margaritas. The bottles I get at BevMo open without problem.

For the uninitiated, here's a killer margarita recipe - Herradura, Cointreau, and lime.
