My first impression was, "Cute cafe like Italian restaurant subtly inserted in a wall of the Venetian!"
You might just walk by this little restaurant if you don't pay attention. Among the many shops and little stores within the Venetian, Trattoria Reggiano may only catch a glimpse of your attention because of their "outdoor patio." It's more just some tables set up nicely outside. Not bad, but I think they do that just to seat more people. Inside the restaurant seats just a few parties because there are about 10 small booths more or less. Their kitchen is tiny! Their ambiance definitely catches the intended theme of an "Italian street side cafe."
It's a cute little place if you're craving some Italian food. Great garlic rolls, almost drenched in the oil and seasonings, some might complain. But I personally really liked it. We ordered the margarita pizza, and a pasta dish that I cannot recall the name of. But neither of the dishes were memorable and I really can't see myself ordering anything other than the basic spaghetti or Alfredo the next time I go there. Mainly, I'd be back for their garlic rolls. The food was okay, the service was okay (slightly rude), the ambiance quaint.
The lasting impression? "I'll be back for some good ol' spaghetti and garlic rolls. But that's about it."
