What’s your favorite mixed drink?

Hi ladies. I have a question for what kind of mixed drink I should ask for at a bar ?

My bf goes to this one bar that’s more of a rough bar. It’s not the kind of place that has margaritas. It’s a place where most people drink beer and mixed drinks.

I’m not sure what to ask for and I don’t want to embarrass myself. I don’t drink at bars much and I normally get margaritas in restaurants.

So what would you order?
