Recs for my itinerary?

Hello! I'm planning a family trip to London next month and I'm looking for restaurant recs to fit into our itinerary. We'd love to get some great Indian food, classic British fare, and any other must-haves you'd recommend!

- Any breakfast or cafes near Holburn station

- Lunch between Buckingham Palace & Westminster Abbey

- Dinner near Buckingham Palace

- Lunch near Victoria & Albert Museum/Natural History Museum

- Dinner in SoHo

TIA!
