Wanted a quick dinner and were staying in the Downtown Grand hotel. O+S is cutesy, upscale diner in decor. We had a fantastic waiter who was helpful answering questions about the menu, which contains standard diner fare with a Hawaiian bent. We wanted to try something new, so we ordered the Moco Loco, med rare, egg over easy. This was so well seasoned it required nothing but your fork. We finished off our meal with the molten brownie. Brownie was mostly sweet, not uniquely flavorful, pretty standard stuff. But entree was enough to earn this place 4 stars!
