Is it a fancy resturant? Like how casual or is a dress and a suit appropriate attire?

Either works. It has a great happy hour, casual yet classy feel. Good food. I wouldn't say I is inexoensive, but moderateky orice

Casual but gets crowded

Casual is fine. Even jeans and a dress shirt is cool. Very laid back.

I just dont want to overdress

There is no dress code. As long as you have a shirt and pants on. I wouldn't have any holes in my shirts or pants. It is a respectable place.
