Two expert mixologists weigh in on the cocktails you should avoid when going out on the town.

It’s your money, and you should spend it however you please, but there are a few things to consider when ordering a drink at a bar. Some cocktails contain far more alcohol than a customer might think, while others are pure sugar bombs. If it’s busy, asking for a time-consuming tipple is a sure-fire way to annoy the bartender. Keeping these factors in mind and with the help of two excellent New York City bartenders, we’ve rounded up 10 drinks you should never order at a bar.

1. Long Island Iced Tea

“This is a drink with a bad reputation because of its strength,” says Sean McClure, the beverage director for the Ivory Peacock in New York City. This cocktail contains vodka, rum, gin, tequila, and triple sec, which may seem appealing for its cost-effectiveness, but it ultimately has far too much alcohol for one concoction. However, if you insist on ordering it, McClure advises that you get just one, otherwise “you’ll end up in trouble.”

2. Ramos Gin Fizz

Trevor Easton Langer, the head bartender for New York City’s Bar Calico, agrees that “it’s your money, do what you want with it,” but he also points out that customers “should be situationally aware.” A labor-intensive tipple like the Ramos gin fizz—requiring egg whites and lots of shaking—can “slow down the entire service.” If it’s a quiet night, go for it, but “when it’s busy, time is money.”

3. Mojito

This drink comes with some caveats. If you’re in Cuba, where the mojito originated, order it. If the bar has all the necessary tools and regularly runs through fresh mint, then yes, absolutely. Otherwise, the key herb required for this cocktail has a limited shelf life and can carry bacteria when spoiled. Additionally, like the Ramos gin fizz, it’s a time-consuming cocktail requiring muddling, so keep that in mind if you want something delivered quickly.

4. Frozen Drinks

Sure, frozen daiquiris and coladas seem refreshing on a hot day, but they are typically loaded with juices and mixers. If you’re trying to limit sugar intake, these icy cocktails are not ideal. Furthermore, the overbearing sweetness can mask the alcohol’s flavor, which may lead you to drink more than you intended.

5. Appletini

Let’s be frank, we’re not in the ‘90s anymore, and our drinks should neither taste like a Jolly Rancher nor look like a radioactive substance. Unless you’re at a high-end bar making the Appletini with fresh Granny Smith apples, it’s time to leave this drink in the past.

6. Bloody Mary

While a few bars have transformed this perennial brunch favorite into an evening cocktail, most have not. “The mise en place probably isn’t even on the bar if you’re ordering this outside of brunch hours,” says McClure. So avoid ordering a Bloody Mary at any other time unless you see it on the menu, or you’ll likely get a drink with an awful pre-made mix and an irritated bartender.

7. New York Sour

Like the Ramos gin fizz, the New York sour is another laborious drink that shouldn’t be ordered if the bar is busy. The cocktail is topped with a red wine float that can create a mess when not properly poured. It also requires a fruity red wine, which may not be on hand, thereby compromising the drink’s intended flavor.

8. A “Surprise”

If you ask a good bartender to “surprise” you, they will likely follow that request with questions about your preferred spirits or flavor profiles. However, unless you can correctly convey your preferences, don’t expect them to be mind readers.

9. Curdled Shots

If you’re contemplating ordering a “cement mixer” or an “alien brain hemorrhage,” just don’t. “They are just gross and belong in a college dorm,” McClure warns. Moreover, they have an extremely unpleasant texture. Whether you’re at a classic dive bar or a trendy cocktail establishment, leave the pranks at home.

10. Flaming Shots

In the age of Instagram, fire certainly has a wow factor, but it’s also dangerous. McClure acknowledges that while the visual effects of flames are striking, he has witnessed numerous instances of people burning themselves on shot glasses that inevitably absorb heat. Therefore, it’s best to steer clear of flaming shots.
