The reigning champ of LA's mobile lobster rolls: Lobsta Truck. Prices are high, but it's still an incredible deal, says janetms383. "Three ounces of succulent lobster drenched in butter on a toasted bun for $12. Outrageous." And WildSwede thinks the Dungeness crab rolls with butter are even better than the lobster ones.
But there's a new competitor in town, Cousins Maine Lobster. GK in SO likes it better than Lobsta Truck: The rolls are tastier, better dressed, and contain more lobster (sustainably harvested, though a bit tough).
Check both trucks' websites for weekly schedules.
