Friend picked up subs there over the weekend (roast beef with mayo, all veggies (including green peppers and black olives) except lettuce, plus hot peppers). Could have use a little more roast beef, but overall was the best sub I've had in a long time. Not sure what size it was, but it was huge. Will be going back there next time I'm in the area.

The best sub shop in all of New Hampshire. USA Subs is down the street from my office and I eat there every week. Their menu offers a wide variety. The grilled subs are my favorite and the employees are friendly. The parking is very limited...but I usually call ahead, park on the side of the building and run in and out with my lunch.
