If you are thinking of the Farringdon area, may I suggest City Raj? It is a great Indian restaurant on Farringdon Street, just under the Holborn flyover. A 3-4 minute walk from the Underground/overland (Brighton-Bedford Thameslink) station.
There are also some great bars/pubs in the immediate area like Smiths of Smithfield, The Last, Bar Ember, The Hoop and Grapes and many more......
