Pre-show meal in Las Vegas

We are spending 4 nights in LV for our 20th anniversary. We will be having a big celebration meal (Picasso)and are eating at Lotus of Siam another night, but are undecided about a more casual meal the first night before seeing Danny Gans at the Mirage. We are considering Onda and Olives. Has anyone eaten at these places, or does anyone have another suggestion in that general part of the Strip?
