Well, in Erie you can go by bus or by cab- there are no trains. Depending on where you stay(ie Hotel Central on Peach St.), like tkim said, you are actually within walking distance of several restaurants and fast food places. In fact, you're within walking distance of nearly everything that matters in Erie(you'll see what I mean) 😀 . My personal preference would be to rent a car- you're going to be here three days and I'm not a big fan of the other two modes of transport. I don't like the bus, my wife who takes it occasionally doesn't like it and I haven't heard very good things from other people. Plus, to my knowledge, the bus doesn't drop off very close to LECOM, so if you had planned to take the bus over, you'd end up walking a good portion anyway. I could be wrong, but I'll just say this- I don't know of any students that take the bus to fort LECOM.
I'll give you a few examples of places on Peach within walking(as in no more than 1/4- 1/2 mile or so depending on where you stay):
McD's, Burger King, Taco Bell, Panera Bread, Applebee's, TGIF, a few Steakhouses, Wal-mart, K-mart, Giant Eagle, etc. If you go farther north on Peach, you get more. Everything in Erie, like I said, is on Peach St.
