The most important thing about your reviews is not the vocabulary or the structure. It's that they sound like you.
The best restaurant critics in the world are all different. A.A. Gill was razor-sharp and theatrical. Jonathan Gold was warm, democratic, and encyclopaedic. Jay Rayner is funny and direct. They disagree with each other constantly. What they share is not a style. It's authenticity. You read them and feel a real person behind the words, with specific tastes, honest reactions, and a consistent perspective.
Your voice will develop naturally as you write more. But there are specific things you can do to find it faster.
Write the Way You Talk
If you wouldn't say "the amuse-bouche was a delightful interplay of textures" out loud to a friend, don't write it. Write the way you'd describe the meal to someone you trust. Directly, specifically, in your own words.
Try this exercise: after a restaurant meal, describe the experience out loud to someone. Record yourself if you need to. Listen to how you naturally talk about food. That's your voice. The written version should sound like that, cleaned up but not transformed into someone else's language.
Have Opinions and Own Them
The reviews that help the most are the ones with a clear point of view. Not aggressive, not performative. Just honest.
"This is the best grilled octopus I've had in Barcelona, and I've eaten a lot of grilled octopus" is a useful sentence because it tells the reader where you stand and gives them context for your experience. It's an opinion grounded in comparison. It's specific. And it's confident without being arrogant.
Wishy-washy reviews that try to please everyone please no one. If you thought the service was slow, say it was slow. If you thought the wine list was exceptional, say so. Your opinion, grounded in specific observations, is what makes your review worth reading.
Develop Your Recurring Lens
Every interesting critic has a lens. A thing they consistently notice and care about that others might not. For one person, it's how restaurants treat solo diners. For another, it's bread quality. For another, it's whether the wine list has depth in the under-twenty-euro range. For another, it's the quality of the olive oil.
You probably already have one. Think about what you notice first when you walk into a restaurant. Think about what you talk about afterward, the detail that sticks with you. That recurring interest is your lens. Lean into it. Over time, it becomes part of what makes your reviews recognisably yours.
Your First Reviews Will Be Your Worst
This is true for everyone. Writing is a skill, and it improves with practice. Your tenth review will be better than your first. Your fiftieth will be better than your tenth. Don't wait until you feel "ready" to start writing. You'll never feel ready. Start now. Write honestly. Improve as you go.
The community exists to help with this. Reading other reviews from credentialed members shows you what good looks like. Over time, the quality of your writing, and the specificity of your observations, will be reflected in how the community responds to your contributions.
