I frequently go to The Keg for client lunches, or even a quick Friday afternoon meeting with colleagues. The food at pretty much every Keg location is pretty consistent - I can't say I've ever had a "bad" meal, but I do find this location slow at lunch.
I would personally recommend sticking to soup and salad, or their larger meal salads if you're going for lunch. I had the steak sandwich recently, and did not enjoy it - it came on a very thick baguette that was very hard to cut - the steak was good but I felt like I needed a saw to get through the bread!
