UPDATE: I've been there twice recently, mostly because of the Painted Hills beef, the quality is still there. The wait staff isn't. Not sure where they were but I have been there three times now and the wait staff is always atrocious. All special orders are still ignored and they'd do better to send you your food with a slingshot.
I'd like to say this concept is a good one: Place your order at the counter and have the staff bring it out. This IS a great concept if you are McDonalds and charging 99 cents for a burger. But when you're charging $7 for a burger and $5 for a salad this is a terrible idea. There's this place called Red Robin, you may have heard of it? Anyway imagine the same prices with lower quality food and no service and you know what you'll get at the Blazing Onion. And, oh yeah, the fries were undercooked and cold and the Hamburger was tasteless. But the bun WAS toasted and was actually pretty good albeit a REALLY expensive hamburger bun.
So they have a good wine list and live music on Friday/Saturday night (occasionally?). This actaully adds to the disjointed atmosphere and makes it a kind of hodge-podge of weirdness.
What were the owners thinking? You don't want to know.
Pros: the bun was toasted
Cons: food, service, bizarre atmosphere
