I'm a long time North Park resident, but somehow never made it over to Crazy Burger, on 30th Street, until this weekend.  Have driven by millions of times, have heard it's good...but just never actually went.  Discovered it's perfect for a low-key evening when you need a hearty meal but don't want to dress; I wore the clothes I was gardening in and didn't feel out of place.  Fun and eclectic crowd, good atmosphere/energy, and decent food.  My partner enjoyed the veggie burger.  (Though I don't recommend the crab-cake burger.)  Great prices on beer & wine.  I like the whole "place your own order and seat yourself" model.  I'll definitely go back.
