I've been to this place a couple of times and I've usually come away satisfied. Not amazed, but not like I had wasted my money.
Personally, I feel that the Pickle Barrel is really just a larger Kelsey's with a bigger & better menu. The food was fairly delicious, but nothing particularly fresh tasting. I've had good service and I've had slow and unfriendly service.
I'm sure this place could be something quite amazing if they simply were a little pickier on who they hired as staff, and upped the quality of their meals, but I don't think they'll ever have that need.
For now, it remains an ol' faithful when you want a nicer version of Kelseys.
