Went to check-out Peters' tonight after recommendations from a friends that used to live in Calgary. The shakes are fantastic, the food I had was mediocre.
First for the food....this is Alberta! Cattle country, I would expect to get some great tasting chuck in these burgers! Nothing. Where is the flavor to these burgers? The bun is nicely made fresh and engulfs the meat patty. Even for a drive-in, I would expect to get some flavor from the burger. Instead it's masked by their "secret sauce" (tastes a lot like Sweet Baby Ray's BBQ ). So disappointing.
Their onion rings are certainly not fresh - but rather frozen from a bag and deep fried. Avoid them. 1 order will feed two people.
They are able to redeem themselves on their shakes. You are allowed a selection of 3 flavours free of charge. The sizes are huge. A small is equal to a large at McDonalds. Nice and thick.
Be prepared to wait.
