When it comes to a grabbing a burger, good value for your $ comes to mind here. By that I mean being near the combo prices of the large chain burger joints with drive-thrus (Carl's Jr, McDonalds, etc), Smashburger's taste blows them away. Also, when it comes to probably the closest resemblance of a competitor in my opinion - Five Guys, they also blow them away when it comes to value and taste compared to your dollars spent.
Numerous reviews describe the menu choices, so I will skip that except the mention of the fried pickles - this is something you don't see at most burger places and my daughter loves these! You can also opt to replace your fries in a combo for these (I think for a price difference).
The burgers have that home made appeal and flavor with fresh ingredients and the way the edges are crispy really make things pop. If you want to make yourself feel really guilty, get one of their shakes that are fantastic and have that old malt shop feeling about them.
Service is not the most speedy but all-in-all a place you should try and should add in to your burger choice rotation for sure.
