Pretty damn good.
The salads are pretty average, and so was the gnocchi, but they call it "Pizza a Metro" because they're known for their pizza...and the pizza is delicious.
I'd go with the vegetarian, I thought it was a lot better than the margarita, which was also pretty good.
Did I mention the people were really cool? They are, and that's important. Plus the bread they give you at the beginning of the meal is awesome.
Let's face the real facts here: You can come to a Metro with some friends and get a really good downtown meal for under $10 a person. What more can you ask for?
