This review is for the park street location.
My significant other and I went here and both got sick. We shared an egg salad sandwich on a bagel. A few hours later we both had seriously upset stomachs. No, I don't have any kind of absolute proof or anything, but it was all that we ate for the day at that point, and it seems highly coincidental that we'd both suffer from the exact same symptoms at about the same time. It took us out of commission for the rest of the day. The egg salad did taste a little funky, and we probably shouldn't have eaten it, but we both assumed that the taste had something to do with an herb or spice they added. I guess we were wrong.
I hope Gotham bagels will make sure to use only fresh egg salad from now on. We're not going to mess with it again. Groannn.
