Came here late at night with the hubs - we were both drunk and hungry. We shared a cheeseburger combo and it was delicious. Before this experience, I've only ever had frozen White Castle burgers that I bought from Safeway (those were horrible). The real deal was much better.
I'd say give it a shot! It's cheap junk food, so of course it's not going to be perfect. If you're coming here looking for a medium-rare wagyu burger, I suggest you take your hipster ass somewhere else. White Castle isn't your fancy gourmet burger shop, it's a quick stop for a quick snack, and it does not disappoint.
