I grew up on fast food just like this! The milkshakes are perfect. Different "flavors" mixed in vanilla... simple and delicious. I had a butterfingers one which I wholeheartedly enjoyed.
The food selection is not targeted to vegetarians, but that's fine with me since I love onion rings and grilled cheese! My boyfriends chili fries looked and smelled amazing too... I was a little envious.
I will definitely hit this place next time I need a shake or some greasy onion rings. I wouldn't eat in, the tables and atmosphere inside are not that awesome, but take out and drive through work great!
