I love the Yard House. (I used to live in LA & the Yard House located on the pier in Long Beach is my absolute favorite place to lounge with friends). The Yard House @ Westgate also has great ambiance. The bar is always a fun place to sit and outdoor seating is enjoyable especially when the weather is nice. Outdoors you can choose to sit in comfy patio chairs with cocktail tables or at regular tables that allow you a view of the center fountains.
Service--I've always had great service from the staff, even on a crowded night. They always seem friendly and fun. They do their best to accommodate and make decent recommendations when you're not sure what to order.
Food--The spinach dip is wonderful as an appetizer. I usually order the thai chicken or walnut pear salad which I always get with the dressing on the side, in case I don't finish. I tried the roasted turkey pot pie once, which is HUGE and could feed 2 easily. It held up well and wasn't half bad reheated....Beer is ALWAYS good. I've never had a beer there that I didn't like and a while ago, you used to be able to buy a whole 'yarder', where they served you a beer in a yard long glass. My out of town guests loved ordering the 'yarder' b/c it was a unique experience.
Cost--I do have to agree with some of the other posters--the prices could be better but I enjoy it there so much, that's just the trade off.
