I have eaten at the Tempe location and in Orange County, both times I was very happy with my burger!
They are grilled to perfection and their choice of "add-ons" are really good! I recently had the char-original with swiss and avocado, I'm hungry just thinking about it!
We also had an after dinner shake- perfect ending to the meal. the atmosphere was nice and clean but really really busy! We felt lucky to get a table, I'm sure in a few months it will slow a bit. Thankfully the wait for food wasn't more than 5-7 min after placing our order at the counter.
Will for SURE be back!
