Had a P.Terry's double with cheese and grilled onions last tonight -- good stuff!
Do they have any secret items that aren't on the public menu? Something along the lines of In-N-Out's "Animal Style", 3x3, 4x4, etc. I went out to their website and didn't see anything listed.
Their drive-thru line does not look like it can handle much traffic. I'd hate to visit around peak hours.
