Oh My Gosh!  In A Tub is only the greatest place to buy tacos ever.  I live in Kansas City, Missouri so maybe it's just a local thing, I'm not sure (we have at least three in the area, so I figured it was a fairly major chain).  Their tacos are really greasy, with really thin, wafery shells.  And the cheese isn't real cheese but powdered cheese.  I know it sounds disgusting but you can't put it down until you've tried it.  I've had people tell me, "No, I don't like real greasy food" or "Powdered cheese? Blech!" But I am here to tell you, every person who told me they probably wouldn't like it ended up loving it.  In A Tub does for tacos what Taco John's does for taquitos or what Taco Bell does for nachos (BellGrandes! Slobber, drool, slobber).  And In A Tub's taco sauce is to frikkin' die for.  It is smooth and tasty and so much better than anyplace I've had, and you can request mild, medium or hot.  Nummers!
