I strongly recommend bringing, $20, a water bottle, pocky and a small backpack. There are freebies when you reg (while supplies last), theres fun stuff to buy so if you don't wanna lose it the backpack is pwnership. There's plenty of restaurants nearby, but if you start to get the munchies and have a panel you HAVE to go to that pocky (or other fun themed snack) will be a lifesaver!
Basically its all been covered here, but if your going bare minimums, that's my suggestion.
Note rite aid = 3-4 blocks, "snacks and sundries" shop is like a block and a half, the quickie marts are both about 5 blocks.
