I don't usually give 5 stars, but Wazzup Dog deserves it!
The best hot dog restaurant in Amman and one of my favorite places in town, their sandwiches are amazing and tasty, you can add whatever you want to your sandwich, Ketchup, mayonnaise, mustard, chips, pickles, corn and onion.
Service is really great and I loved the decor, especially the drawings on the wall.
Prices are good, 1.85 per sandwich. Highly recommended :)
