If you're looking for high quality meats and great service in the Conejo Valley, then Mastros is your best option.
The dimly lit dining area is quaint, but feels very exclusive. The menu is straight forward and beef is the main attraction. Everything is A La Cart and the portions of the side dishes are enough to share. There is a nice assortment of bread, there is a full bar with a nice wine list.
Our meal started off with an order of Fanny Bay and Blue Point oysters and a couple of wedge salads. The oysters were served with fresh horseradish, cocktail sauce and lemon. The oysters were delicious, the wedge salads were typical, nothing to write home about.
For our entrees, I had the Veal Chop, we also ordered the Bone-In Filet and the fish of the day, which was Halibut. For our side dishes we had, Lobster Mashed Potatoes, Macaroni Cheese and the Sauteed Asparagus. The meats are served unadorned, there are no sauces and no garnishes. My Veal chop was cooked perfectly and the seasoning was on point. I had a taste of the Filet and it was delicious. But the side dishes always seem to steal the show. I love their mac and cheese, made with five cheeses and browned nicely on top. At this point I'm completely stuffed. But the dessert selection is pretty good.
We ordered the Vanilla Gelato and Creme Brulee, our declared that this was not enough. And since it was my birthday, he said he would bring out something special. So in addition to the gelato and brulee, he brought out Mastro's signature dessert, the Warm Butter Cake. The plate was decorated nicely with a birthday message written in chocolate. If you go to Mastro's, you have to try the warm butter cake. It's ridiculous and I don't even like sweets.
The service at this location is impeccable. Our server Bobby, answered all of our questions and offered many great suggestions.
In my opinion Mastro's Steakhouse is a great option. I like it better the other "chain" steakhouses like Ruth's Chris and Flemings. Though it may not be at the level of CUT or Wolfgangs, the prices are much more reasonable.
