It seems like there is some confusion over opening hours. I have just spoken with Saagar and confirmed that they're open for lunch five days per week (Monday to Friday) and for dinner seven days per week.
(We've been up there after work a good few times over the last two weeks to arrange the deal and can testify that they're open! Perhaps the person who answered the phone misunderstood, and was saying that they weren't currently open for dinner?)
rick_fantastic, I'll PM you and we can either book it for you, or arrange a refund if you're prefer.
