When I first heard of this eatery and saw a picture of macaroni and cheese with meatballs, I thought, "This place was invented for me."
So I went there and ordered the meal I saw in that photo, which was $12, taxes included. The macaroni and cheese was good, if a bit too salty, and the meatballs were very tasty. The portion was a pretty good size, though I would've preferred a bit more.
The decor was kind of lazy - casual to a fault. But decor isn't a big factor when I rate a restaurant.
I think a few of the negative reviewers here don't understand what kind of place this is supposed to be. Someone wrote that the meatballs were dry. They were indeed a bit on the dry side, but this isn't a regular restaurant; their goal is basically to provide quality fast food, and that's exactly what I got. They don't cook the food after you arrive; they prepare it. You pay when you order, and they call your name for you to come to the counter to get it. If that's not the kind of restaurant experience you were looking for, go elsewhere. As far as I'm concerned, Hey Meatball delivers exactly what it aims to. I look forward to going back and trying different dishes.
