I'm a vote for Logans... they're second best to the now closed roadhouse grill.
I know here, they run the two meal special for 13.99 mon-wen nights. On top of that, each meal comes with two sides, so plenty of food for nearly the price of one entree. For two people you can walk out with a tab under 20$ (plus tip).
My cousin runs a slightly more upscale casual steak place. And I love eating there, definatly the best steak ever, but if it wasn't for family, I would never go eat there. Too expensive for my water budget.
