I have eaten at the airport location a few times and many times at the downtown hub. I agree with other reviewers who say the airport location is not as good, but disagree to go somewhere else as all terminal B food places are mundane.
Its the best in terminal B but the service, quality & quantity do not measure up to the original...management needs to improve this location as not many people enjoy getting so-so sandwich & service for a $12 (without chips/drink), even at the airport.
One positive I'd mention is that they have a small seating area in the back with a nice view and it hasn't been crowded the times I've been there. It's a nice place to eat, see the planes go buy and ingest 8 oz of corned beef, sauerkraut and thousand island dressing, yum.
