you probably tried something to fresh and real, if that makes any sense. try easing your way into it with tempura rolls, or even the eel roll since its cooked. then when your comftorble with that try moving up to something else, maybe a tuna roll and then finally try sashimi. but even sashimi can be hit or miss with people that like conventional sushi
I love sushi, there is lots of all you can eat sushi places here in Southern CA $20 for about 1hr, everything on the menu to choose from. Even the lobster rolls
