We were celebrating my husband's 65th birthday, by going to an exhibition at Tate Britain, and wanted to have dinner afterwards, somewhere close by. After a bit of Googling, I found Osterelia Dell Angelo, which had excellent reviews. I did call them to check if...I needed to book, and they suggested it wasn't vital, but would be a good idea, so I did. The person I spoke to was charming, and I did mention it was my husband's birthday. After the exhibition, we arrived a few minutes late, and we immediately liked the look of the place, and all the staff we dealt with were absolutely lovely. Small details impressed us, such as the linen tablecloth and napkins, fresh flowers, candles and comfortable seats. The menu is limited,, but we like that because it shows that the food is probably prepared properly. We I chose a cocktail and a Peroni, to drink while we were choosing our food, and my cocktail was a delicious Rossini. I decided to go for a starter and dessert, because I don't have a huge appetite. I went for the burrata with oyster mushrooms and pistachios, and my husband's main course was the monkfish with leeks. We also had sides of rosemary, roast potatoes, and the marinated beetroot. We chose a Sicilian organic wine to go with our meal, with our food and it seemed very reasonably priced at £28. They also brought four types of complimentary bread with olive oil, and an amuse bouche of deep - fried pizza dough with sauce. The portions were generousand beautifully presented, as well as delicious. The highlight of our evening, however, was that when they brought my dessert of tiramisu, which we shared, they had put candle in it, and had written "Happy Birthday" around the plate. The waiter even sang Happy Birthday, which was really sweet, and very much appreciated! Everything about the evening was lovely, and even the toilets were stylish and immaculate. Whilst visiting them, we discovered a really nice private, dining room downstairs, which I can imagine would be a lovely venue for big, family party, or some such thing. We were actually pleasantly surprised by the size of the bill, which even including 12.5% service, was less than £130 pounds, considering we had coffee and tea afterwards as well. For the quality of the food in that part of London, it seemed extraordinarily good value. We would certainly go again, and can't recommend it highly enough!More
