The third pitch, though short, features a some interesting climbing and is very popular.
P1 climbs 3 cracks in a cave to a chimney finish (60', 5.5), P2 is short, and takes you out on a exposed fin into a series of awkward and exciting high-step moves (bolt protected) to gain the chains for Eat Yourself a Pie 40', 5.7).
P3 climb up above the anchor underneath the left side of the roof. Make a move right to the handcrack in the roof. Step around the lip and continue to the top (5.9).
The third pitch may be accessed via Eat Yourself a Pie (5.8+), which shares an anchor with the P2 belay.
