I'm coming to London soon and I've been asked to make dinner reservations for 2 near the Wallace Collection, but I have very very limited experience with London restaurants and don't even know where to start. I'm hoping to stay w/in walking distance of the Wallace (maybe 20 minutes?) and keep the price around 40-50 USD/person. I'm finding many gastropubs (which are fine, as long as the food is solid and it's not too rowdy or loud) or things well out of my price range. Any thoughts? Many thanks!
