If eating alone then The MOAT at the Wheeler centre is good. Friendly, cosy, has books and newspapers available and many people eat alone.
In addition you can often catch something at the Wheeler centre to stimulate the mind.
It has the added attraction of no doof doof music and the likely hood that most people there have read at least one book. Not something you can say about every place.
