I say 3.5 for good measure. It's definitely the best bang for your buck in the neighborhood. Simple place, simple interior, simple service, simple deli/diner type menu. The $3.99 breakfast cannot be beat. Have had lunch a couple times, tried the chicken pita on the first go round; which was great, and the corned beef Reuben with potato salad on the second. I enjoy a Reuben with soft thick rye like the kind they use here, but I wouldn't say it tasted like an authentic "NY deli reuben". Potato salad was quite tastey, you can tell its made in house and not from a tub. Yellow based, and tangy as expected.
The best part- one of the cooks is a Deadhead, so if youre a fan too, the conversation can be quite entertaining :)
