Time Out says
A classy looking Italian restaurant in Belsize Park, Il Primo looks like it keeps things traditional. The food menu is a Who's Who of classic Italian dishes, while the wine list keeps things focused solely on the boot.
Dishes range from bruschetta and bresaola with rocket and parmesan to king prawn risotto, rigatoni with chicken, courgette and white sauce, grilled sea bass with mixed salad, asparagus and lemon dressing, and rib-eye steak served with truffle mash. Desserts include tiramisu, panna cotta and crostata di frutta fresca.
The wine list includes bottles from across Italy, with some options available by the glass and by the half-bottle.
