How to Spot a Fresh Seafood Restaurant

Freshness is hard to judge from a menu alone, but there are a handful of practical signs worth checking before you sit down, most of which take under a minute.

Ask a Real Question, Not a Generic One

Ask what's landed that day, or what the catch of the day actually is. A kitchen that genuinely changes its offering with what's available will have a real answer, not a generic one, often because it's sourcing through a market like Billingsgate rather than a single fixed supplier. A vague or rehearsed-sounding answer is itself a useful signal.

Check the Fish Itself

If a restaurant serves whole fish, the eyes should be clear and slightly bulging, not sunken or cloudy, and the flesh should spring back when pressed rather than leaving a dent. On a fillet, the flesh should look moist and slightly translucent, not dull, dry-looking, or discoloured at the edges.

Use Your Nose

Smell matters more than most people use it. Good seafood should smell clean, faintly of the sea, not fishy in an unpleasant way. If you can smell a strong fishy odour from the door of a restaurant, that's usually a sign the fish isn't as fresh as it should be, or that the kitchen isn't storing it properly.

Look for Seasonal Honesty

Menus that change with the seasons are a good sign too. Native oysters are only really in season roughly September to April, so a restaurant offering them as a fixed, year-round item without saying so is worth a second look. A kitchen that's honest about seasonal availability, and swaps dishes accordingly, is usually one paying closer attention to sourcing.

Trust the Numbers, Not Just the Room

Finally, don't ignore how a restaurant is actually rated by people who've eaten there recently. A high rating built on hundreds or thousands of reviews is a far more reliable signal than a handful of five-star ratings from a restaurant's opening week, or a nice-looking dining room on its own. If sourcing specifically matters to you, what "sustainably sourced" actually means is worth reading too.
