Isis is fantastic, well worth the price. Service is outstanding. Food is amazing.

Some more I remembered -

Liquorish - How could I forget this place! One of my fav places in Brisbane.

Ahmets - use to love it but went there a few months back and was slightly disappointed. Food didn't seem as nice. And I could barely hear anything over the music from the belly dancers!

Sono - awesome Japanese. The sashimi is amazing and I love how you sit on cushions.

And for best coffee and muffins I like Modena on Adelaide Street. Though I hear the Italian guy who owned it has now sold it
