Firebirds has solid food but not anything that really stands out. I've never had a bad meal here but I've also never had an amazing one. Firebirds the type of restaurant you go to when a) you're dining with someone with a less adventurous palate or b) you're in a big group and want a variety of entrees to choose from.
They have a fairly large menu of basic anerican standbys: fish, chicken, steaks, and burgers. They do all of these things fairly well from my experience and I've been here many times since my mom loves this place. I'm not a liquor drinker but I've heard their cocktails are good.
The reason that firebirds isn't in four star territory is that the food, though fresh and decent quality, just isn't that flavorful. Based on their current menu, it looks like they're trying to do more creative things with their good by offering various sauces and different encrusted fishes but they just haven't mastered using these flavors to enhance the food. Case in point: I got the chili rubbed delmonico last time I was there but didn't taste any chili though the steak itself was solid. I had a similar issue with the green chili mac and cheese (a shame because green chili is awesome and not something that shows up often in restaurants outside the southwest).
In summary, thus isn't a place I ever choose to go to on my own but I also don't protest when my mother inevitably suggests it during my visits.
