Easily one of the best burgers I've ever had. I opted for the Riverside sirloin burger, it was perfectly cooked and the toppings were great. I was impressed by the bacon, not burnt to a crisp like most places but fresh and still a bit soft. Wasn't busy at all when I was there so service was great, but I'd be interested to see what it's like when it's packed. Kudos for serving coke in the big glass bottles, even if it was a bit expensive. A hefty cut above the usual diner experience. Definitely eating here again. Extra points for their Paleo bun option (not a bun at all, they wrap the burger in a lettuce leaf!)
