I spent nine days in Tel Aviv in mid-October. I've written on my blog in a bit more detail about where and what I ate (including photos - some are better than others!)
With that being said, I can say that Tel Aviv is one of the best eating cities I've been to - fresh and local ingredients, really innovative preparations that reference both local cuisine and others from around the world.
I think my favorite meal was Gedera 26 - amazing house-made bratwurst. Plus a cilantro pesto served before the meal was phenomenal.
And Cafe 48 had really great food, along with the friendliest service I encountered. It was the one place I visited twice!
