Bluefin is one my top ten sushi spots in Las Vegas.
Although their AYCE menu isn't as good as other places in Chinatown, they are conveniently located near my school in Henderson so I can't complain. I love how their sushi is really fresh and thick. Although the rice to sushi ratio isn't the best (because let's be real, we all prefer more fish and less rice) the quality of fish is worth it.
Plus, they have an affordable lunch special menu that include a miso soup and chef salad with all the dishes. I always order the Sashimi Special Combo for 15.95. It is a 10 piece sashimi dish that includes: tuna, yellowtail, salmon, shrimp, white fish, miso soup, and house salad.
