I've been waiting for a deli (particularly those that serve corned beef and pastrami sandwiches--and if I even wanted to get more picky, I'd prefer it be Kosher or at least Kosher style) to open up on campus the past three years. Thankfully the Beef Stand just opened with relatively inexpensive prices (so far)! You can get a corned beef sandwich (hot or cold) on marbled rye for $5.50. It even comes with a pickle on the side!
The corned beef has a relatively mild flavor compared to what I'm used to at home, but if you're craving deli food, this place will hit the spot (at least until you go home to Bagel & Bialy, Max & Benny's, The Bagel, etc). By no means is this place any competition to those I just listed above, but it's definitely worth a try.
A few criticisms: the corned beef and pastrami here are chopped into little pieces and not sliced like a traditional deli will do. Also, if you prefer to have a hot sandwich, be prepared to see the cook throw your meat onto a flat top grill. Completely wrong.
I would give this 3.5 stars if I had the option. However, this is a huge improvement for the traditionally lackluster campus town.
