Well, we went back again, with a friend who hadn't been to Kaya in a few years. We accidentally hit a happy hour we didn't know about, and had a half hour wait for a table; no problems. The bartenders basically ignored us for fifteen minutes while we sat there - seated at the bar - and that kind of soured the tone.
The portion sizes were opulent, and most of the food was excellent. But one of the appetizers was just straight up burned; it'd be hard to respect the food you're serving *and* let that out of the kitchen.
A-OK, since it averaged between excellent and terrible.
