PASADENA. Perhaps one of the region’s best sushi joints, ultra-sleek Sushi Roku may not attract the trendy model-and-starlet crowd that its West Hollywood and Santa Monica siblings get; nevertheless, wise Pasadenians take full advantage of the Japanese “comfort food” (some of it prepared on an open-flame grill). Diners looking to go the raw route should consider sampling something from the sushi bar, like miji, katana with cucumber, crab and avocado, and sea eel ­ there are far too many choices for just one visit.
