You can't go wrong getting a soup and salad at Panera Bread in Southlake. This time I tried the Greek Salad and a the Broccoli Cheese Soup. Both were excellent! The next time I go, I am ordering what my son got. The flatbread sandwich and the black bean soup. He was very pleased with his selections. I have signed up for Panera Bread Rewards online. I have been rewarded with free desserts, and a health shake or beverage. I am in LOVE with the carrot cake muffins.
I agree that during peak business hours, it is difficult to find a place to sit. Lots of "business" meetings going on. Do yourself a favor and go at a strange time like 3:00 and finding a clean table won't be a problem.
