The burgers are decent, and the concrete's are great. I like that if you order a concrete or sundae they will hold it back till you are ready for it so it won't melt. Another thing about the concrete's are that they are huge. The few times we've been there I've needed to share the smallest size because it is too much custard.
The unfortunate side to Freddy's in my opinion is that their chili tastes canned (I know it's from a can, but not everywhere tastes like straight up Hormel chili from a can, which is nasty), the fries suck and are flavorless, unless greasy is the flavor you are going for, and if you order the chili cheese fries they come standard with a gross cheese sauce and in order to get real cheese you have to psychically know that real cheese is an option that you can ask for.
Honestly this place is ok, not great, but definitely better than the other steak burger and shake place near it.
