I drove down to That's A Burger yesterday (Thursday night) at about 6 PM. The storefront is hard to find; I recommend taking Stony Island down to 71st and making a left so that you are on the south side of the train tracks, then turning making a U-turn at one of the yield signs right before South Shore Drive to head back west. You can then park easily right in front of the place at a meter.
Was at TAB a week ago myself - the above is almost exactly how I always
get there (I usually take Cottage Grove, and then Stony Island, followed by
a left on 71st). You dont actually *have* to make a U-turn - there is
metered parking across the street too.
When I picked up the sandwich it was piping hot, wrapped in white waxed paper within a paper bag. Surprisingly ungreasy, the inner package revealed a generous handful of seasoned fries, deliberately moist as opposed to crispy, which is characteristic of the South Side. The sandwich featured a generous 1/2 pound of buttery ground beef with a great steaky taste and aroma. Thick-cut bacon, chopped petals of grilled onions, and vinegary jalapeno peppers (you can also get giardinera, which I might try next time) offered a perfect contrast. The bun was very fresh, refined white flour with no seeds, untoasted, but offering just the right soft chew to offset the char of the beef and crispy edges of the bacon.
I'd rate this the best stand-up buger I've ever had, matching the pleasure of my favorite sit-down affairs at Moody's (on a good night) and at Duke of Perth. I have been less thrilled with the consistency at Poag Mahone's and the Avenue in Oak Park, both of which can deliver a winner on some nights and a very standard sandwich on others. The bottom of my regularly visited spectrum are Twisted Spoke (get the pulled pork instead) and Goldyburger in Forest Park, which on multiple visits have only produced C+ or B- hamburgers for the price.
While I do like the TAB burger a fair bit, I wouldnt rate it amongst my Top Three
of all time

Even so, it *is* very good. Up on the north side... have you ever
tried Paradise Pup? Not quite the sort of place that TAB is, but they too
do a very fine (and similarly cheap) burger. For sit-downs, Jury's has drawn
much praise here. A few weeks ago (after TOC's rec), I tried their #2
"cheap burger" at Lion Head Pub (its a buck on Tuesdays, I was in the
area about 4pm-ish and stopped in... it was a very quiet place at the
time, and the burger was really pretty good).
Would you say that TAB's single-burger is a 1/2 lb, BTW? Id have guessed
smaller... maybe a third or so.
I highly recommend the trek down to That's A Burger. Give that nice couple some business, see a beautiful old street (71st), and walk away with a smile. I found this photoblog describing a similar experience to mind:

Id add my rec for TAB - a very nice burger. If you ever go at the "busy time",
however, expect a wait - everything is cooked to order (as you saw), and
its 10-15 minutes without anyone in line, usually (lots of phone-orders come
in). At really busy times, its been up to a half hour - calling ahead may make
sense. Or, if you want a snack while youre waiting, there's ia Harold's
Chicken next door
Thanks to bjt in this thread too - will definitely try the Souith Shore Cultural
Center next time for the TAB burger (better than eating in the car, which is
what Ive done every time so far).
