I've been here quite a few times over the past couple of years.
I've been very impressed with both the products and the service. They carry a number of unique oils and vinegars, which you can sample before buying. I love that you can buy as much or as little as you want. You do have to buy the containers but you can always bring them back and fill them up again after they are empty. I think the prices are fair considering the high quality. The employees are always very helpful, even when the store is crowded (which seems to be only on Saturday afternoon).
I honestly think I eat more salad now because I have these great salad dressing ingredients and that is definitely a good thing!
