Not near the B&B as it's a *little bit* more rural. There's more near the HIE since it's located at an interstate interchange. There are some places within a couple minutes of the venue. You mentioned you're staying at a Marriott or something like that near downtown Newark so you'll be close to lots of restaurants since you're on a university campus.
There is a breakfast/lunch place called Guildays around the corner from the venue I've never been to but, the parking lot is always packed and I've considered stopping sometime.
The three areas are not like a city where there is a lot in walking distance but, there is a lot within a 5 minute drive in several directions from the venue, HIE and B&B.
