Is the following review positive or negative?

As badly as I want to try new Indian restaurants in town, I always end up leaving utterly disappointed and regretting my decision for not just going to Mint (my never-fails-me staple). Taj Palace was no exception. Things had started off well with a nice interior and friendly service. But then everything started to go downhill from there with a total blowup to end our meal. -Food took much too long to come out. -Free papadums were nice, but the tamarind and mint chutneys tasted old. -The garlic naan had no traceable amounts of garlic, plus it was super crunchy and almost burnt. -$5 for a bowl of plain rice. -The aloo gobi (or gobi aloo as they call it) was completely flavorless (at an Indian restaurant??). It was just boiled potatoes, cauliflower, and tomatoes sitting in some liquid. Not edible. I will give credit where credit is due and say that the Paneer Tiki Masala was very good. It was flavorful and had a generous portion of paneer. The kicker was at the end when we went to pay for our meal and we were told they wouldn't accept our coupon. It would have been one thing if there was a sign posted on the door stating this or if we hadn't shown the servers the coupon until the end of our meal. However, there is no sign saying they don't accept coupons AND we had the coupon out at the edge of the table from the minute we sat down. FOUR servers never once said anything about it before we ordered, despite the fact that I saw all of them look at it. I'm tired of restaurants offering coupons and then deciding they don't feel like it anymore and won't make good on the ones that are still out there. But to wait until after we are done eating to tell us, when you know that we have a coupon waiting, is shady to me. It's times like these I wish my mom didn't raise me to be polite and just walk away from the situation. The paneer was their saving grace that brought them up to two stars.
