Sushi 21 has been delighting Oceanside diners for 8 years. It offers a range of Japanese cuisine, from rice bowls, sake and of course, plenty of sushi. It boasts an all-you-can-eat special while the attentive service keeps customers coming back. Lunch specials run around $10 for Bento Boxes, sushi combos and the other specialty, the udon combos. Non-sushi specials include the seafood curry and the interesting ham & bacon fried rice. And after a couple Kirins, be sure to jump on the karaoke machine and the owner just might join in for a duet of Beatles tunes!
