Fire & Stone is in Covent Garden so is quite expensive usually. The Raspberry Bellini (prosecco cocktail) that is included would normally be £8 and the main courses are £10-£12.
Maybe not such a great deal then if you don't get 2 dinners and 2 puddings
The deal is for one person, so I guess you can just order the Valentines menu and go on your own!
Looks delicious- If you don't have anyone, can you go there and eat both dinners and desserts?
