Lime olive oil + Blackberry vinegar = Margarita flavor
...Which believe it or not, makes a killer salad dressing. There's an olive oil and vinegar tasting bar set up all throughout the day where experts can show you how to properly taste and mix flavors of olive oil. This is actually very interesting and I guarantee if you do this, you'll walk out with a purchase.
In the back they have a little patio with an awesome view where you can enjoy a glass of wine and a cheese/meat platter. The food is very good.
I go here also to buy gifts. I will say that it's not inexpensive, but you get what you pay for. They also have mustards and other spreads too. You can bring in bottles from home for them to fill with olive oil and vinegar, which is obviously very eco-friendly.
