@Spago Restaurant every pasta I've had is excellent (my personal favourite is the "pasta scraps" with eggplant and ricotta), their arancini is delicious (complemented by the blue cheese sauce), and their goat cheese salad is mouthwatering. They also serve the best tiramisu I've had in Amman.
@Cushions Lounge they have buffet for 5 JD's and if you want a side order it's for 8 JD's and it includes: cheese, hummus, labaneh, salads, omlette, qalaiet bandora, mofarakeh potato, hot dogs, saj, um ali, layali lebnan, bread and tea
to be honest; it's very difficult to find a job as a 16 year old, but you can check @LOYAC they usually hire college students but give them a call a check if they are willing to have a volunteer to help in their programs ( homes, innovation camp, community service) you can ask them about these programs.
@Skyline Sushi I loved the place, great atmosphere and delicious food. I would 10/10 recommend to everyone looking to eat sushi, the menu is diverse and the service is quick.
