We've eaten at Saffron once. The food and service was very good, particularly the Amritsari Fish appetizer, which was amazing.
We"ve wanted to try the lunch buffet for a while, so we stopped by on a Sunday. Their websight does not post times for the buffet, so I figured they most likely didn't offer it on weekends, with the expectation that buffet seekers would just eat there anyway.
Not only was that the case, but they also had a sign on the sidewalk advertising the lunch buffet that they didn't have. I took the picture on Sunday, when they have no buffet. Bait and switch is just a dirty business practice.
For a truly amazing Indian lunch buffet with published times, try the place at the northeast corner of Bell and I17.
