I was a picky eater too. I love places like Applebee's. But I went to V&A with an open mind the first time - I promised my DBF that I would try at least a little bite of everything. Now I wish I knew where I could find things like squid ink pasta (absolutely delicious), buffalo (no not the wings, but the meat - better than any steak I have ever had), and pheasant (very yummy). We have been to V&A three times and the only thing I didn't like was the pears poached in port wine. We have made a pact to go once every trip.
I would recommend that you send your son and his girl friend some where else and enjoy one of the best meals you will ever have! If you like wine, I would recommend the wine pairing as well.
Oh and make sure you are hungry. The portions may look small but that is very deceiving!
