I tried their Fuku burger and it was delicious. It was very juicy but I think it is because there was so much sauce not because of the beef. It was so busy and expensive because their burgers are small. It wasn't very worth the 30 minute car ride, the 15 minute wait in line to order, and the additional 20 minute wait for them to finish making the order. All this for two burgers that cost $11. It was a new and different experience though. The crowd was a little creepy - it seemed like everyone present at the time were loitering stoners (or stoners just waiting for their orders).
It was around West Tropicana at the time I think, in a small strip mall close to a smoke shop. It can be cool hangout spot if you come with larger groups of people.
