Unfortunately I didn't stick around long enough to see all the responses to my query on friday. I did stop at Kirby burger, and had an underwhelming experience.
I didn't think the pattie was that bad, it was hand made, cooked nicely (just slightly pink), and had a nice bun. Important for a good burger.
My bf had the "extreme" burger with kirby sauce, bacon and cheese and I had the kirby burger which came with the same special kirby sauce. This was the not so good part. It was touted as a special blend of mushrooms green peppers and spices. Well, the mushrooms were canned, the green peppers nonexistant and the sauce itself was completely tasteless.....it looked sort of like the sauce for beef stroganoff but without any taste.
As far as the sides....I had a shake which was good but not amazing, and onion rings. It's hard to screw up onion rings. My bf had the fries, which are fresh cut but weren't cooked enough so were still a little cruncy in the middle.
The reality is that I don't think I'll go out of my way to stop here again. However, I got great fireworks from the truck!
