This funky little eatery in the South End has grown quite a bit (not in size, but in appeal) over the last few years.  What started as not much more than a rather ugly yellow cinder block building on an oddly-shaped lot is now that and more - they've added some landscaping, a paved lot instead of the gravel parking and a nice outdoor eating area too.  Inside the food is the same great, simple combinations you're used to getting.\n\nThe cramped quarters also haven't changed much, but that's just part of the appeal.  As strange as it may sound, the sheer volume that moves through this place makes it possible to place your order and get a table by the time the order is ready - provided everyone cooperates and doesn't hog their table out of their place in line.  When you're done, get up and let someone else have the table, and everything keeps moving as it should.\n\nTable tops still contain business cards from around town, and there is plenty of artwork to see as well, and the atmosphere is worth coming for, but it's the food that should keep you coming back.  While the burrito is the namesake of the place, make sure you try the quesadilla too.  They are excellent.
