This is definitely at the top of my list when I want a regular Italian meal without all the fancy decor and overpriced food. I've had a lot of experiences of going to "upscale" Western restaurants (usually Italian), paying a premium for the fancy decor while getting mediocre food. Grazie offers many pasta and pizza options at fair prices. And most importantly the taste is awesome!
There's something for everyone. They have a very good selection of pastas and pizzas. Cream sauce, tomato sauce, pesto sauce, you name it! If you want wine, they have too. The ingredients they use are very wholesome. Service is nice too. And their menu is easy to navigate.
It's no mystery why this place is always packed.
