I went to the Exhibit's launch of their new 393 menu last night- yes thats a starter for £3, main course for £9 and desert for just £3.  I tried the fish cakes to start and steak ciabatta for the main- both were delicious.  Unfortunately I didn't have room for desert.   I have to confess I hadn't actually eaten in the Exhibit before.  The restaurant had a really nice ambience and the service was good.  A really good value night out.  To book a table call 0208 772 6556 or email exhibit@exhibitbars.com
