What is the sentiment of the following review?
Good service but disappointing food. Our California burger was dry... Which is hard to do given then mushrooms on top. The buns were stale. My pear salad was full of flavors that just don't go together. We usually don't eat at places unless they are 4 stars. We made an exception on this one and we are bummed we did.
