This has to be the #1 question I've been asked over the years. People walk into Starbucks, see the unfamiliar terminology on the menu boards, get overwhelmed and feel completely lost. That's one of the reasons I started a website waaay back in the early '00s with drink info on it, to help people navigate the menu.
The problem is, “What should I order?” is a hard question to answer without context. It's like “What should I order at McDonald's?” or “What book should I buy from Amazon?” To give a useful answer, you need to know the asker's preferences and what they're in the mood for. I'll list some of the more common things people have in mind here and my suggestions for what to order. And remember — when in doubt, ask the barista.
I just want a coffee. Go ahead and order a coffee, that's totally allowed. If they're in the middle of brewing a new batch, or if they've stopped brewing the coffee you want for the day, they may offer you an Americano, a French press, or a Clover brew. All of those are pretty good options.
I want something kinda sweet but not too expensive or fancy. Try the vanilla latte. It can be made hot or cold, depending on what temperature of drink you're in the mood for.
I want that thing that's like a coffee milkshake. That's a Frappuccino. The most popular flavor is usually the Mocha Frappuccino, followed closely by the Caramel Frappuccino.
I need something with a lot of caffeine to wake me up. Try a venti (large) vanilla latte with an “add shot”. That will get you three shots of espresso in a moderately sweet drink. If you want to up the ante more, make it a quad (four shots). Careful not to overdo it, though — know your caffeine limits. If you need a lot of caffeine but don't want it to taste like coffee, get a venti white mocha with an addshot instead. It will be more expensive, but the white mocha syrup is very sweet, to balance out the espresso.
I want something with no coffee at all. There's lots of options. Want a hot drink? Try a hot chocolate or a chai latte (this has tea in it, so there's still some caffeine). Want a cold drink? Grab a passion tea lemonade, a vanilla bean creme Frappuccino, or one of their new Fizzio sodas.
I'm a tea drinker. You can get a regular tea (there's several varieties to choose from) or a regular iced tea, as well as a line of tea lattes and chai if you want something more than just tea.
I want something caramelly! For a hot drink, get the caramel macchiato (mah-kee-AH-toe) and make sure you stir it well before drinking. For a cold drink, get the caramel Frappuccino.
I need to get something for my kid. The pastry case usually has some milks and juices to choose from. You can also get a kid's hot chocolate (it's an 8 oz cup, and not steamed as hot as adult drinks), an apple juice, or a vanilla bean creme Frappuccino (this has a lot of sugar in it, however). If your kid wants something different, ask the barista if they can make it with no coffee, or at least decaf. Be aware that decaffeinated coffee is not caffeine-free, so it's best to avoid coffee-based things entirely later in the evening.
I'm vegan/lactose intolerant. Most espresso drinks can be made with soy milk. Be aware that the basic flavoring syrups such as vanilla and hazelnut are made with sugar, so if that is an animal product concern for you, avoid these. Seasonal syrups such as pumpkin spice may contain milk products; check with your barista to be sure. When I worked for Starbucks many ages ago I was told that the mocha syrup was vegan, but I don't know if this is still true. Your barista should be able to check the ingredients on the package or syrup bottle if you have questions. If in doubt, stick to simple drinks like coffee, tea, or the juices in the pastry case.
I'm diabetic/on a diet. Plain coffee and tea are extremely low in calories and sugar-free. However, if you need more sweetness in your drink, sugar-free syrups such as sugar-free vanilla are available. Most Frappuccinos can be ordered Light, which reduces the calories and sugar by about half. For more detailed information, check the nutrition info on the Starbucks website.
That covers the most common “what should I order?” questions I get. If you've got a request that's not on the list, leave it in the comments and I'll make a suggestion. And like I said before, you can always ask the person behind the register for advice. Be ready to give them a rough idea of what you like (hot/cold, sweet/not sweet, coffee/tea/neither, etc). And if you don't like what you get, let them know and they'll probably be willing to make you a replacement drink! (Just … don't drink the whole thing and then claim you didn't like it and demand a new drink. They may humor you but they've seen that con game before.)
