Sushi Den and its sister restaurants on South Pearl Street have long been the standard for high-end Japanese dining in Denver, so when group co-founder Toshi Kizaki and chef Kenta Kamo opened a spot inside the Source in RiNo, diners took notice. Now four years into its run, Temaki Den has a deserved reputation for excellence, dishing out aburi (or flame-seared sushi) and hand rolls (temaki) assembled in front of diners who are instructed to eat quickly and efficiently so as not to upset the delicate balance of the perfect bite: crispy nori, warm rice and cool fish.
