Reviews from YELP:

"A friend of my husband was in town this weekend and wanted to grab sandwiches from this place.  My husband and I weren't feeling too hungry and were unsure if we were in the sandwich mood.  Lucky for us, we decided to go along anyway and got two of the best subs we've had in a long time.  The Lucky Seven (turkey, melted swiss, russian dressing, and coleslaw) and the Unforgiven (roast beef, melted provolone, BBQ sauce, and potato salad) were equally heavenly.  The coleslaw and potato salad INSIDE the sandwich is pure genius.  We ordered small subs but the next time we'll be sure to get larges.  There's really not a large seating area (just a few small tables outside) so I suggest ordering to go.  We actually called ahead so our subs were ready when we came to pick them up.  You can bet we'll be hitting this place up again really soon."

"This is what a sandwich place should be.  Friendly, quick and with some amazing menu choices.  The Unforgiven is my favorite sandwich in boston, bar none."

"We also love the lucky 7.  GO, and when you do, be sure to ask for your free pickle!"

Review from CitySearch:

"In Short – 7 Subs does a strong takeout business among area workers, and customers rave about the shop's plethora of options. The "Lucky 7" combines Turkey, coleslaw, melted Swiss and russian dressing, while the "Wilbur" include black forest ham, American cheese, lettuce, dill pickles and yellow mustard. Homemade soups (Hungarian mushroom, beef barley with vegetables) and fresh salads round out the offerings."
