Really like the concept of small 5$ portion, especially as a small eater myself!
I'd say stick with the salad, and fresh produce inspired options. We tried these 4 items : Gravlax salad, Ceasar salar, Fish Taco, Shrimp and Beef burger.
The salads were great, full of flavour and ingredients. The taco was good, and the burger disapointing, a frozen McDonalds like dry patty with 2 shrimps. I don't mind the burger being a bit smaller perhaps and getting a nice fresh -notfrozen patty of meat.
Oh well, would come back for a salad! (Or perhaps desert?)
