While cruising down University killing some time, my friend noticed The Chuck Box, and stated that we had to go there.  Other than the obvious mentioning of hamburgers, we had no idea what to expect, but based on the fact that it was a little wooden shack that was spouting smoke, we assumed it HAD to be good, and right up our alley.\n\nLater that night after a Fall League baseball game, we decided that it was the perfect time to try The Chuck Box.  The parking is a little sparse, but there was space for me, so no complaints there.  The exterior is about as dive-y as I would have guessed, to no complaints there either.  Upon entering, the interior is total dive, wooden walls, tables, benches and stools.  No velvet ropes here, but a bigass chain to separate those in line with the rest of the customers.\n\nI ordered a Big Juan, and savored the pleasant aroma of a slab of beef going onto the grill right before my eyes.  It was cooked perfectly to order, and I took my time at the condiment area to load it up with what I like.  But not too much to eliminate the flavor of the beef, which was cooked just right, still a little juicy, but nice and warm, with good natural flavor.\n\nMy only knock on it is the cash-only policy.  There is an ATM there, but typically I don't carry cash on me, but since I was being all touristy, I was prepared.  But that just meant I had to pay for my ill-prepared friend who was being too cheap to get decked with ATM surcharges.\n\nOtherwise, The Chuck Box was a fantastic find, and well worth the experience, and was a fine burger overall.
