Enoteca San Marco is located in St. Mark's Square which can be hard to find if you are not overly familiar with the Venetian. One of my friends chose the restaurant because she wanted Italian at a moderate price. In those two regards, Enoteca San Marco met our expectations, but in terms of amazing service or quality of food, I was totally let down. Sure the food was fresh, but it didn't have any wow factor at all.
First, you have multiple servers throughout the meal (I think we had about five during our meal) - I much prefer having only one or two servers that I can build a relationship with throughout the course of the meal. My group started with a cheese plate (burrata, fontina, and parmigiano reggiano) which came with three different items for us to dip the cheese in (the group's favorite was the honey). For my dinner, I had the Bavette Cacio e Pepe, which is really just pasta with black pepper and cheese in olive oil. It was very basic, but the pasta was very fresh. Two of my dining companions had the spaghetti and meatball special, which they both loved especially because the meatballs were spicy; another friend had the spaghetti and zucchini in olive oil special which she said was very fresh; and my other friend had the butternut squash and braised pork shoulder. While we all enjoyed our meals, we were not wowed at all. However, our dessert did have us raving - we shared cream puffs and each of the three had a gelato flavor of our choosing. The almond gelato cream puff was by far our favorite.
While my portion of the wine and meal after trip was $48 which I didn't think was that bad, I can't say I was very impressed with Mario Batali after visiting Enoteca San Marco and I am not running to go visit another of his restaurants anytime in the near future. Definitely 3 stars.
