Do yourself a favor and order the Shack Stack. Please. Yes, it's $10, but it's absolutely worth it. Probably my favorite burger of all time.
There's also hot dogs, custards, milkshakes, and plenty of other burgers out there for you to choose.
I've tried their chocolate, strawberry, and peanut butter milkshakes, and they were all very good. Fries were fine, nothing too special.
Seriously though, order the Shack Stack.
