I love Freddy's! We go there a lot. Their burgers are good, hot dogs are good, patty melts are GREAT. But the pièce de résistance are their glorious little french fries. They are super seasoned, matchstick size bits of goodness. YummY!
I've never actually had their custard, but it looks pretty tasty. I've gotten it both to go, and sat inside to eat. The inside of the restaurant is super clean. The employees are very friendly.
If you do drive through, you have to wait for a bit - but that's because they are making your food fresh, it wasn't sitting under a heat lamp for 45 minutes. So...overall, 2 thumbs up. :)
