Core does look exactly my kind of fine dining from reviews and from seeing your photos. I actually tried to go on a recent trip to London, but it's understandably a bit too popular for one of my usual last minute trips. I ended up at Sketch Gallery (the newly 3* minted Sketch library was unsurprisingly full) which has unfortunately gotten uncomfortably "instagrammy" since I was last there and is no longer such a fun place to hang out and just enjoy the scenery. So. Many. Girls. With. iPhones.
