Stopped in for a Super roast beef sandwich- the Super is on an onion roll (yum) while the other roast beef sandwiches are on a sesame seed bun. Constantine has been in business there for over 40 years- had a great conversation. Quiet on a Sat as much of his business comes from local businesses and students from the nearby high school. Heard great things about the pizza rolls- didn’t get to try them today, sold out from all the students. Will definitely go back. My beef sandwich was fantastic.

I rarely leave negative reviews, but I feel compelled to share my experience at Mimi’s Roast Beef & Seafood. From the moment I walked in, the owner/employee gave me attitude. When I asked for a 3-way roast beef sandwich, he just stared at me. Confused, I clarified my order, only to be lectured about sandwich sizes (junior, regular, super) in a condescending way that made me feel like I was being talked down to. I brushed it off and ordered the largest size, but when I returned to pick up my food, he began yelling at me for having a service dog. He told me, “Don’t come back here again… with your dog.” I found this behavior unprofessional and unacceptable. The food may be fine, but the customer service was terrible. One star is more than fair — I would leave zero if I could.

Pretty good roast beef. Colder beef than the usual NS beef but also cooked a little more which I like. (The typical NS completely raw beef grosses me out). You got to love the owner though. He's been serving beefs for like 40 years, waaay before they became a foodie fad. So if you say 3 way to him he'll look at you like you're a giant dork. I think its hilarious. But anyhow the food is pretty darn good for fast food. Oh and the prices are fair. He didnt jack up his prices 200% when 40-50% inflation hit over the past couple of years. He jacked up the prices to pretty much exactly what the inflation was.

The roast beef is cooked perfectly. It is cold but it is really really good. The BBQ sauce made that sandwich smack. I give them an 8 out of 10. I'm glad I stopped by.

Roast beef is great! Super thin and a toasted bun! Very simple but in a good way!
