We were there a week ago Saturday.

I ordered a Calgary Burger, Smashfries and chocolate shake.

My wife ordered a Calgary Burger, onion rings and an Oreo shake.

My kids both ordered the kids burgers and fries, with one having a vanilla shake and the other having an oreo shake.

The total came to $52.

The Calgary Burger was good, but not "OMG Good"; I'd certainly order another one but they aren't good enough for me to go out of my way to get one.

The Smashfries were nice and different from most fries I have had; I tried a few without ketchup and then decided that putting ketchup on them would probably ruin the uniqueness so ate most of them plain only trying ketchup on the last few...better without ketchup IMHO. Again, good, but I'm not going out of my way to get them.

The onion rings were nice and the sauce made them better; not too greasy. As above, good, but not enough for me to go out of my way to get them.

The kid's burgers and fries were very ordinary.

The milkshakes were absolutely fantastic and I would go out of my way to get one. We all tried each other's shake and all were great.

The restaurant itself felt like a typical fast food restaurant.

They deliver the food to your table when it is ready and give you a number to place on your table so they know where you are. They brought out my meal and the two meals for my kids, but not my wife's meal; I asked the guy when the other burger was coming and he said that was it, I told him that we ordered two Calgary Burgers and he asked to see my receipt and then went and got my wife's order.

They were friendly, but I'm not sure how the order ended up on my receipt but not in their system...it was only their third day of operation though.

The final price gave me some sticker shock, but in fairness the shakes were $5 each adding $20 to the meal; at South St. Burgers the family meal is about $32 including pop, 4 burgers and two large sides, so minus the shakes (but adding two pops for my wife and I) would have brought the price to within $5 of South St.

One nitpick, we ordered the kids meals and asked to substitute shakes for the included soft drinks with us paying the extra, however, they wouldn't do that. We had to buy the kid's shakes separately and still got two kids pops. Most places these days have the ability to add something different to a kids meal with us just paying the difference...that Smashburger can't do this is disappointing.

Our primary "higher end" burger place is South St. Burgers and comparing them I would say:

I prefer the burgers at South St. over those at Smashburger...South St. has a tasty seasoning that I really like and you can choose from a lot of different toppings.

Smashfries and Smashburger onion rings beat the greasier New York Fries and onion rings at South St. South St. has just changed their onion rings and I haven't tried the new ones yet, but I found the old ones really greasy.

I can't compare the shakes because I haven't had one at South St., but the shakes at Smashburger will be tough to beat, they were the highlight of the meal and I would go out of my way to have another one.

TL;DR: I found the burgers, fries and onion rings good, but not great, the shakes were great and I highly recommend them.
