I tried the Thai burger, and I loved it—a substantial portion of chicken with a spicy Thai sauce. I will definitely come back for another one.

Tried all three meats and was really good. Will be coming back. It's better than Dubai's McDonald's, halal and on top of that you're not supporting genocide :)

Delicious smash burgers! They are a bit small so I would recommend getting 2 but prices are really good. The employee recommended this platter for 4 people (4 burgers, 8 tenders, large fries and 4 drinks), and it was a great late night snack. They also have other options such as regular burgers and chicken sandwiches.
