Depends on if you want to walk all the way through the commerce of DTD (longer) or take a bit of a convoluted, but shorter, way.
Longer, commerce-filled walk is just go out to DTD, walk all the way through it. Get to DLH, turn left (Compass Books will be over to your left). You'll see PP, enter, follow signs to PCH Grill.
If you would like a shorter walk, though a bit twisty and turny, then go out to DTD, and walk until you see Haagen Dazs on your right, then on your left is Sephora and Libby Lu. There are gates to GCH between Sephora and Libby Lu. Enter those gates. Turn right. Follow the walkway, go in the automatic doors, follow the now inside walkway, go up the sets of short stairs (or the ramps over to the right if anyone is on wheels). Once you enter the lobby, turn right almost as soon as you can, and go out the pretty pretty huge automatic sliding doors (if it's a busy time you won't see the doors b/c they'll be open, so just go outside, LOL). You'll see PP, so go out the driveway (using the sidewalk of course), cross the street at the crosswalk, enter the front of PP, follow signs to PCH Grill.
Sounds more complicated than it actually is.
