I really wish I had had a positive experience, but both times, such a disappointment! In Mill Valley we bought half a pound of halibut. When we got home it was such a small cut, we decided to weigh it- a quarter pound for $19!
Yesterday we stopped to get tacos. My yellowtail taco was completely undercooked. Raw on the inside. I had to cook it once home. When I spend $36 on four tacos I expect it to be delicious and cooked to perfection. It seems like they must be good at times, its too bad my two experiences have been so bad.
