If there was a 6th star this place would get it. It's amazing how the entire staff is fairly young (early 20's to early 30's?) yet they are probably the most professional and classy staff I've experienced, anywhere, ever... They are ALWAYS on top of things, very friendly, very efficient and from the taste of the food it's no different in the kitchen. I just can't say enough good things about their service.
The food itself is absolutely delicious and they have a pasta special, $5.99 for Spaghetti and Meatballs on Monday and Tuesday nights. It's a generous portion, very filling and very gourmet tasting.
The atmosphere is top notch and even when they're very busy it never takes too horribly long to get seated.
Other Phoenix Businesses should go spend a day at Babbo's to learn how to be successful.
