I failed on the pictures due to some greasy fingers, so apologies there. I'd go back for round II to get some pics but my stomach was just bored the last time around and I'll try the fajitas.
The burger is actually not bad but it is also not interesting in anyway. It's as though a committee at corporate picked out 10 criteria they agreed characterized a "Classic American Burger" and demanded every burger be put through that cookie cutter, damn the local conditions, different ingredients, etc. The beef patty itself is pretty good, quality meat but you really see it in the bacon. For all practical purposes there is no real bacon in this country. Nonetheless, TGI Fridays tries to trick you by taking Argentine thick ham and trimming it and frying it to look like bacon, and they kind of succeed but that is obviously not the point.
If you're looking for an acceptable 'American-style" burger in BA you won't be disappointed but there much better places have sprung up in the past few years and you won't have to deal with as much fake Americana, stupid hats and Flair!.
