El Romero

The entire menu at this sustainable, seafood-focused kitchen is gluten-free, and they’ve got tasty vegetarian dishes like the chilled ajoblanco, an almond-based gazpacho that comes with crunchy seasonal vegetables. The friendly owners pick up the daily fresh catch from Mercat des Peix, just a few steps away, and whip up things like prawn tartare with truffle and white chocolate, or the wild fish of the day in hollandaise. There’s a sunny terrace that overlooks the back of Maó’s cathedral, but if you can’t get a seat there, the interior is also lovely and full of bright, exposed masonry that gives it an old-world vibe.
