I cook every valentines, something a bit different to our usual pasta or pie. Today we have fillet steak with shitake mushrooms in a miring rice wine sauce with ginger and garlic. Last year was duck with strawberry and raspberry sauce. But will never go pay silly money for a crap fixed menu from a restaurant the whole day is a con.
Mind you, works better in Japan, I remember when we lived there 14th Feb was for the men, 14th March for the ladies - they have two days!
