The world often values complexity, but there's something to be said for taking an idea back to its purest form -- like rock music with no amplification, just a crap ton of super weird drugs. Bringing the old-school back to sushi: Fishlips.
Started by a couple longtime sushi men, Fishlips claims to be the US's first fresh mobile sushi lunch truck, abetted with a massive window to see the food's preparation and inspired by raw fish's roots as an affordable street-food cart-snack in pre-Hello Kitty Japan. The fish's all fresh, straight from distributors and made to order w/ warm rice (rather than pre-packaged and refrigerated); straight-up swimmers come 2-per-order, served in the rice-ball-with-fish-on-top style known as temari and thrown on the menu with both its proper name and English translation, i.e., unagi (eel), hirame (halibut), and "white tuna" -- apparently Japanese for both albacore, eskalar, and "our translator is dishonorably uncreative". They also offer up a slew of creative rolls, like the Red Dragon (avocado, cucumber, crab, mayo, green onion, tuna, hot-sauce, sesame oil), the Long Beach (shrimp tempura, avocado, cucumber, white tuna, pepper, red onion, ponzu sauce), and a soy paper/avocado/cucumber/asparagus roll with six types of fish and hot sauce simply called "Fish Lips", either 'cause it's the owners' trademark, or because the lawyers would be all over "Spicy Joan Rivers".
As per usual, Fishlips' location's trackable via their website and Twitter (generally they're Westside-ish, in the Venice/Westwood hoods); unusually, the menu's also got a calorie count for each morsel -- cause a calorie's just the purest form of energy available, assuming you're out of drugs.
