Reviews for the Oasis were either great or terrible, so naturally my wife and I had to see for ourselves. We happened to drive by it as we were exploring the city and were underwhelmed by its appearance. It appears to be situated in a former Dairy Queen and seems somewhat rundown from the outside. Inside it was somewhat dark and rundown, but we were committed to giving it a try. We ordered a half fish and chips and a Philly cheese steak (which was touted in reviews of the place). The fish and chips were excellent and the Philly was very good though not as good as Geno's or Pat's in Philadelphia - but not many are.
Service was decent and prices were reasonable by Fairbanks standards. We both agree that the reviews praising the place were much closer to our feelings about it. It is definitely worth trying.
