Agree with poster re 4Gats - really cheap at lunchtime when you often have to queue for a table; equally fab at nighttime, not as cheap as lunchtime but great value in comparison to Ireland - had a memorable dinner a couple of years ago, the works incl wine, liquers etc for about €75 for 2. Lunchtime menu about €10 (had that too). Picasso used to hang out there, designed menus etc.
