I generally avoid cold roast beef sandwiches because the meat is either way to rare and grosses me out or way too thick, fatty and chewy but the promise of blue cheese drew me in and I'm so glad!
I did a 1/2 sandwich and salad combo ($7.50) and opted for the roast beef and blue cheese which has delicious sweet and sour caramelized red onions and peppery arugula to elevate the flavors from "packing a punch" to "round house kick." I wish I hadn't been so motivated by the blue cheese that I would've noticed there was mayo - something I'll have to remember to ask them to hold next time... makes sense to have it but I just don't dig mayo, with the rare exception. For my salad -- still cheese beckoning -- I enjoyed roasted red pepper, goat cheese, sun dried tomato and pesto on a bed of mixed field greens. There were a variety of cool chip flavors (and, of course, the standards).
Bertha's was on my radar because they always have a plate of Bertha's cookies out where I get my hair done. You also get a 2-bite cookie with your lunch combo. It was a yummy double chocolate of some sort. I just wish I could've picked my flavor!
An important note about the roast beef on this sandwich: it was so moist and tender. It had a lovely rosy pink to it. Memories of my sandwich inspired me to look for roast beef while getting groceries this weekend but the selection did not compare... so it made me wonder: will Bertha sell me a half pound of roast beef to go?
