This was our second choice of restaurant whilst in Siena; the first place was closed and my travel mate had read decent things about Zest elsewhere.
First off, the gals inside were AMAZING. So friendly, so accommodating, so sweet (and gorgeous to boot!). We were delivered our meals very quickly and oh. my. gods. My gluten free spaghetti and ragu were to die for. I was very adventurous on my trip abroad, but felt I had to try a simple ragu somewhere and I'm so glad I did so at Zest. My mate's pasta was perfect, too. Our roasted potatoes were way too much to eat, but still so good and I had to beg the servers to take them away so I would stop eating them. My mate's chianti she ordered was apparently divine, as well.
There was a bit of a snafu with some American girls in the restaurant and the waitresses were still so wonderful to them, even though the tourists were being sort of (innocently) jerky. That's some serious good service there.
It's harder to recommend a restaurant to everyone that's not in your own back yard, but please please PLEASE, if you're going to Siena, stop in to Zest. You will not regret it.
