I absolutely LOVE the Buy 1 Get 1 Free Sushi deal. Before finding Shiki 2 years ago, I had never really tried sushi because it was too expensive and I was afraid I wouldn't like it. But you can't go wrong at Shiki, everything I've tried has been delicious.
I really like eel ( which I was nervous about trying but it doesn't taste anything like what it sounds like-- it has a very pleasant sweet taste) so I switch between the Sweet Dragon Roll and the Eel Fashion Roll. They both have eel and avocado, but the Eel Fashion also has cream cheese in it.
For my second roll I always go with the Shiki Crunch roll that is topped with crunchy tempura crumbles and delicious eel sauce (a sweet, thick sauce not actually made from eel, just traditionally served along side eel dishes).
At any other sushi place I either walk away still hungry or having dropped a ton of money. At Shiki I'm full on sushi for only $12.
Pros: Great Deal!, tasty, varied menu
