Serving breakfast and lunch all day, Mr. A's is located in the heart of Roselle since 2016. We are a family-owned diner that caters to our customers and strive to have every patron leave happy and full! Known as the ham headquarters of Roselle, we offer a variety of breakfast and lunch dishes using our fresh sliced ham. We also have ham available whole or by the pound for purchase, which are a customer favorite for all holidays. Stop in and try out our menu today. We are open 7 days a week from 6 a.m. to 2:30 p.m.
