Been going here for the last 7 years for lunch when in the office. I have seen it getting busier each time which is a good sign. You can get a roll or a baked potato with fillings of your choice  and the have a daily changing salad bar which a lot of people like but for me the real stars are the daily changing warm meal options and quiches. They do a fantastic homemade steak pie and have nice homemade burgers. Good selection of drinks and snacks as well. Nikkis is celebrating 20 years whilst other sandwich shops in the area have come and gone so they must be doing something right. They are in my eyes.
