Are you saying it's too expensive, or you don't like it? I don't consider Zo to be that expensive considering the cost of sushi these days. My last two meals there with drinks were around $100 per person.
I don't think the quality to price ratio is there. My last meal at Zo was $400+ after tax and tip for 2 people. I haven't been to Q yet, but their prices are similar if not higher, and from what I've seen, doesn't seem worth it to me.
