Pink Pepper is terrific. The only thing that would make it more terrific is faster service and updated decor. But if you want authentic, tasty, spicy Thai food, you won't be disappointed. It's probably the best Thai I've ever had.
I've only been for dinner twice and both times we were thrilled with our choices. I am always blown away by the coconut/chicken/mushroom soup - it's ridiculously good and I could eat 4 servings. We've had various other items and they were all terrific, but I was NOT a fan of the Thai BBQ Chicken (basically a really bland, whole-BBQ'd chicken, cut up with a basic sauce.)
If you're a fan of spice, you will be pleased with their 10-point scale. I thought I could handle my own, but even a 6 was intolerable for me.
Reminds me of the great food in the Bay Area - definitely worth trying.
