Oasis Is excellent, and shouldn't be missed for he the following reasons:
1. Quality: fresh ingredients make these juices and sandwiches stand out where others are bland in comparison. I've never had a more flavourful vegetarian panini.
2. Value: considering the quality of the fresh fruits and produce used, as well as the generous portion-sizes, oasis prices are very competitive.
3. Service: really friendly people run this business!
Basically, this place is a hidden gem that I regret not trying sooner.
