I've never been but my wife went there every so often when she worked downtown a few years back. From what I recall of her reviews, I believe it's a medium to large restaurant (though I think she mentioned kind of weird shaped/layout), nice decor, but expensive (kind of caters to the downtown business crowd). Don't think they do carts.
[I'll double check/edit my post once she gets home.]

Wife confirms that it's more geared towards the biz crowd downtown. About 200-250 seats. No carts. Had a number of mirrors to make the place look bigger. Great view of the harbour until they started construction on the expanded convention centre.
