This is literally the best sandwich you will ever eat! I have been coming to the beast for 5+ years now and have never once been disappointed. If I could give it 10 stars I would. Go with a large, onion roll, roast beef (duh), your favorite cheese, and sauces. Make sure you don't skip the lettuce, tomato, and sautéed onion! Spicy pickles are to die for. I cannot recommend Roast Beast enough, or often enough!
It's been a little while since I'v been into the Roast Beast, but I used to frequent this small sandwichery pretty often on my way from BU. If you like roast beef, this is a very good choice. I can't say anything for their turkey option-- but also I feel like if you're gonna go to the roast beast you're not doing it right if you don't get the beef. My preference is simple withe some hot mustard and horseradish cheese. But there are lots of other options with regards to condiments. With regard to the staff, honestly, they are the reason I went in half the time. I really like DJ and the rest. They are always very friendly and constantly chatting with the other customers. I really haven't left a lot of reviews online, but I feel compelled to when I really have a good experience with the people. Because at the end of the day, I feel like warm company can make the biggest impact. And the staff at the Roast Beast have really raised my spirits at times.
