This Jack in the Box is so scary, at least for me. I can't come here at night anymore. I'll be honest and say that during daylight hours it's almost as decent as a 2-star... But I still wouldn't recommend you to try this location. Its on the corner of Flamingo and Swenson, very dark area though.
The customers and people lurking around this area seem very sketchy/suspicious. Wierd things happen whenever I come to this locaion. I would go through drive-thru whenever I can only to avoid the bums around this place. I only come here because it's less than a minute drive from my apartment. The food quality is as every other Jack in the Box. The service is a little below average, kind of slow, once had to be asked to park in the parking lot because the 24 hr drive thru was "closed". I give props to the workers though, being able to deal with their customers who come in and out of there using their bathroom without purchasing anything.
Also, everytime I use the drive-thru they're always out of desserts, so much for late night cravings...
On the bright side, theres another Jack in the Box on Maryland if you do decide to find another Location. (I'll warn you that its not that much greater of a location either but theres more light there.)
