Clos Maggiore is a romantic restaurant offering a French full-dining experience in Covent Garden. Their plant room, which is a conservatory filled with cherry blossoms, is breathtaking and a great place to take someone for a special meal. The a la carte menu has a few vegetarian options, such as the roasted pumpkin & pine nut soup as a starter, and the oven baked goat’s cheese as a main.  There is also a full vegetarian tasting menu, which costs £65 for 5 courses. The experience here is very French and formal, so perhaps not ideal to visit with a large group.
