Costco Chicken Salad, $3.99 + a drink $.55, plus tax will put you 4 pennies under $5. I go there at least once a week during weekdays. I also get to sample some free food, and check out the big screen TVs, or the latest wines if I have time. I always go the one on technology blvd, which is a short drive from my office.
By the way, not sure others have noticed, the costco food court has been very busy.
