I was on a similar quest last year and did eventually find Thick. However, I think the best deep dish in town is at Good Neighbor. http://goodneighborpizzeria.com/ Hot, deep, and cheesy, exactly how I like my women.
THICK has excellent sausage. It was amazing. I can't help but feel this will be one of those "here today, gone tomorrow" type of food carts though. :-(
@samantha: just checked in with the cart. He's not doing the late night hours any more (although they're still posted on his fb page). It's for rent because he says he's planning on moving to the spots at 9th and Washington as of Sept. 1! Hope that helps!
Thanks, Andrea, I was wondering the same thing about the "For Rent" sign. This dude makes a decent pie, but yet another food cart owner who could do wonders for his business with a little social media communication and time consistency.
Got there, and found... For Rent sign. In 3 separate places on the cart.
Luckily, the Egyptian food next door was open, and makes the very best falafel I think I've had forever.
