Seated upstairs, in a quiet, smart dining room, we perused the menu. Up front is a list of tempting Spanish and Italian bar snacks, all hovering around £4. Then it gets fancier: expensive charcuterie and cheeses, and a selection of equally pricey small-plate fish, meat and vegetable dishes. Our lovely waitress suggested three dishes each would sate our appetites. I agree with Dos Hermanos about eating tapas in a smart restaurant setting - it doesn't feel right. Tapas is traditionally served at the bar, to accompany drinks, often in rowdy surroundings. Sitting at a dining table with starched napkin on lap to graze off starter-sized offerings takes a bit of getting used to. But it's all the rage right now (Polpo, Polpetto, Bocca di Lupo, Terroirs, Morito do it, and do it well).
Crispy Iberico Pigs Ears £3. Delightfully chewy and salty. Pork scratchings with bite.
Patata Fritas with Alioli and Bravas sauce £3.75. Bland, perhaps, but they were polished off quickly. They might be more pleasing if they were cut thicker and had more substance.
Grilled scallop with butternut squash puree, shallot and truffle dressing, and migas £4.25. Refined, and exceptional. The sweet soft scallop melted in the mouth as the salty crunch of crumbly migas added bite, and the fresh dressing gently amplified the scallop. A memorable mouthful, and worth every penny.
Moorish marinated Iberico pork £2.95. One of a selection of skewers available from the charcoal grill. A little disappointing, as the meat was raw in the middle. Bites of London review had the same experience, so it seems I wasn't just unlucky. Fine if you're munching through a stick of beef, but not pork.
Courgette flowers stuffed with goats' cheese and drizzled with honey £7.55. A popular dish at Opera Tavern's two sister restaurants. This was bang on: oozing, salty cheese and sweet sticky honey bringing the humble courgette to life.
Salt marsh lamb leg with pumpkin gnocchi, salted anchovies, brown butter, and mint £6.50. Another hit. Perfectly cooked lamb, and light-as-a-feather gnocchi, with enough butter to leave an indelible impression on my arteries.
Braised short rib of beef with polenta, cavolo nero and sage £7.25. This reminded me of Jun Tanaka's great braised featherblade of beef at the London Restaurant Festival in Spitalfields last year. Soft, rich, and intensely beefy (for want of a better adjective).
And to finish, a tart of chestnuts and something else. I don't remember. It was perfectly decent, but not memorable. Keep your budget for the savoury big hitters.
Our lunch bill, with 4 glasses of Prosecco, came to £80. Too pricey, by far. A fellow food blogger, Lizzie aka Hollow Legs, was at the soft launch, and warned me beforehand on Twitter of the exorbitant prices (click here to see her review), which will put me off returning for now, regardless of the largely impressive meal.
