I recently review the Star Alliance Business Class Lounge at LAX where breakfast options were primarily served.
I recently returned again, where breakfast was just ending, and lunch offerings were being served.
I will just focus on the food in this review.

There was a melon salad, grapes, and cut watermelon.

There was a mango and peach smoothie, and pumpkin rice pudding.

Rice Krispie treats were also on offer.

There was a salmon teriyaki type dish, rice, and vegetables.

There was a vegetarian Thai curry soup.
Pita chips and crackers were also offered.
There was a selection of cheese and dried fruit.

Several different types of salad were also available.

A flat bread sandwich, a wrap, and vegetables were also offered.

In all, the lunch offerings were pretty substantial, especially for a domestic lounge. Although there was really only one hot entrée on offer, several types of salads and sandwiches were available.
I have another upcoming trip, and will have the opportunity to visit the lounge again. If different things are being offered I will have another review.
