Excellent shakes both hard and regular. My son let me try his Salted Nutella Crunch and it was easily the best shake I've had in years. The burgers were pretty good but the toppings seemed to just haphazardly slapped on my burger - two small slices of tomato stacked on top of each other. The onion rings were a big disappointment, five rings for $8 and the rings were slightly undercooked.
Verdict - definitely go if you like shakes and burgers but skip the onion rings.
