Went there once but it was donkey years ago... think in
2000/2001. Well, it's like the jap version of Marche, where you
will get a card to record the food that you order from the various
counters/stalls, then pay at the exit using the card when you are
done.
Prices were pretty steep, around $15-20 I think, and I din see much
variety then. Ended up eating a kids' set for less than $10 (cannot
remember price liao) but it was really cute, with yakitori sticks,
a bottle of yakult and a free magnet! Served in a cartoon rocket
place too 
Good ambience cos a lot of cosy corners for nice chats, but guess
unless you are on a generous budget of around $20-25, you won't
want to start there for long cos cannot eat anything cheap there,
haha...
