I can't speak to the ambiance because a friend brought take-out. My turkey burger was delicious and my companions enjoyed their sandwiches (tuna melt and pulled pork). My fries might have been tasty had they not been limp and sad (in comparison to the turkey burger which was still quite warm). Our side of pita and hummus was disappointing. The pita was so old it had turned into extra chewy lavosh. Eating one piece gave my jaws a workout. The hummus itself was super extra mediocre. There was something off about it.
I may try Tryst again but I certainly won't make a special effort.
