MaMa Kelly is situated in the Olympic Stadium, designed by Dutch architect Jan Wils for the 1928 Olympic games. The restaurant covers 1000m2 divided over 4 floors. At the time we were there it was fully booked and packed with, mostly, women. Be sure to make reservations (mama-kelly.nl) The style of the interior leans towards the glamorous Hollywood Regency style. It's also reminiscent of Sketch in London. Eitherway; it's a nice environment.
