Sei Sushi in San Carlos serves fresh sushi, creative rolls, and Japanese rice bowls from 8862 Navajo Rd, San Diego 92119, in a Navajo Road plaza near the intersection with Lake Murray Boulevard. Established in 2012, Sei Sushi has spent over a decade building a neighborhood following in San Carlos, and the same plaza houses its sister boba operation at R&B Tea San Carlos, where a Sei Sushi receipt unlocks a cross-promotion. The roll menu splits into traditional cuts — tuna, salmon, yellowtail, cucumber, avocado — and creative builds including the Navajo Crunchy Roll, a baked-roll lineup, and a no-rice option wrapped in soy paper for low-carb orders. Nigiri and sashimi platters feature tuna, salmon, yellowtail, and albacore, and a three-item combo at the lunch price point includes any three rolls plus miso soup. San Diego sushi searches run 6,600 queries per month, and Sei Sushi's position on Navajo Road — away from the denser sushi competition on El Cajon Blvd — gives it a geographic lock on the San Carlos and Del Cerro residential base. Beyond sushi, the kitchen runs a ramen program with a 24-hour pork-and-chicken-bone broth topped with pork belly, soft-boiled egg, bean sprouts, mushroom, and scallion — a San Diego ramen entry that competes with the dedicated ramen shops closer to campus. Japanese-style fried chicken (karaage), takoyaki, agedashi tofu, and Korean BBQ fries fill out the appetizer menu, and the bar pours sake, Japanese beer, and wine on tap alongside the food. Lake Murray's walking and running trail puts Sei Sushi within a short drive of the post-exercise crowd, and Cowles Mountain hikers heading south along Navajo Road pass the plaza on their way home. The Navajo Road food corridor also includes the independent grocery tradition at Keil's Fresh Food Store, and the two businesses anchor a strip that serves the 92119 residential base. A health-department score of 95 out of 100 and multiple TVs running K-pop and live sports complete a neighborhood sushi bar that owner Seong H. has maintained in the same location since 2012.
