The place was great. The burgers were juicy and flavorful. The butter bun was similar to a Brioche bun and just as soft.
They have many options for side dishes and cheese curds were interesting. I still prefer the curds without any breading or deep frying, but they were still good.
The custard was outstanding. It was creamy and full of flavor. The concretes end up being better than a DQ Blizzard since the custard is better than the DQ ice cream.
Based on the many different options, this is a place that could give In and Out a run for its money in California. It beats 5 Guys easily.
