Purim Oak in Towson
Purim Oak is actually a korean restaurant. They have an all you can eat sushi bar which I've never tried but I've seen worse in Baltimore. I don't think the all you can eat sushi option is available on weekends, but I would call to double check. Anyways, the korean food there is actually quite good...not as good nor as cheap as the Baltimore korean restaurants but it has better decor.
