I've taken to skipping breakfast on TK TATL flights to enjoy the Lounge. There are crowded areas and there are quiet areas. The lower floor is almost always quiet, as is the far end of the upper floor. For some reason most folk congregate at the front of the lounge.

The lounge has rooms with single beds as well. They're provided to J pax with 4+ hrs (I don't think its restricted to TK FFs only but I may be wrong), and to TK's own Elite Plus.

My favourite features of the lounge are the food and the lockers (a real great feature). Entry is controlled by boarding pass scanners and automated gates so you can enter and leave at will. No interaction with lounge dragons.

MLLs are alright - certainly better than UA and CA at their respective hubs.
