The staff at the Lyon's Avenue location is more professional than the Clinton Avenue location. They are too slow at the Clinton Avenue location as well, even if you call in an order. The last time I was at the Clinton Avenue location I was there waiting for someone too take my order, after 15 minutes of waiting I just walked out.
I thought it was just me, I had called ahead for 2 fish sandwiches and left to pick up the order 20 minutes after I ordered them and still had to wait 20 minutes for my order and like you I walked out. My dead grandmother could move faster.
