We ate at this place two out our three nights in San Diego! We were staying at the Hotel Del and stumbled upon it our first night (they could take 5 people, last minute), and loved the food. The sushi is excellent and creative, and the restaurant is very accommodating and child-friendly (we have three). The next night, we doubled up with family and again, Yummy Sushi was able to accommodate us quickly and graciously. The service is warm, and the kids ate everything! I particularly liked the nigiri (aji and sake). Oddly enough, San Diego was a real disappointment in terms of quick service, but Yummy Sushi was the exception. We'd definitely go back.
