The prizes are really very high but considering its in Marina Bay Sands shopping mall I'd rather say it's OK I understand. One falafel sandwich with French fries and soft drink is about S$20.
We had a falafel and a veggie shawarma sandwich meal. And I must say I had eaten much better. The pita was definitely the weakest part, most probably these preordered microwaved ones but for sure not made there fresh. The falafel was good and they were made fresh for us but the veggie "meat" in the shawarma was completely cold. The good thing was that both sandwiches had a lot of tasty salad and veggies in them. With the french fries together you have a complete meal which makes you definitely full but I wouldn't say it's very healthy.
