If you are traveling to Israel very soon and if you love unique, tasty and high-quality meals, I encourage you to read this blog post by Debbest Israel. I would love to visit some of the restaurants (listed in the blog post) upon returning to Israel in the near future.
Having been to Israel myself, I can say that you will find a lot of great or dynamic places to eat in. There is always something for the food enthusiast or tourist with different tastes or preferences.
