I wanted to start a thread about things to snack on while wandering around center city. Not full meals, just something to tide you over. My thought was, nothing bigger than a slice of pizza - and nothing with waiter service, either. Carts are fine, order at counter and sitdown/take out also fine.
Getting some little snack is something I wind up doing pretty much every time I go downtown. I'll list my suggestions (most of which are pretty obvious), but I'm curious to hear others.
Soft pretzels (incl. millers' at RTM)
ice cream at capogiro
hot dog at underdog (17th and Sansom)
desserts at Miel
canoli from RTM or di bruno's (though I find that di bruno's has fewer other options than I had expected)
for a slice of pizza, i'll usually go w/ Joe's on 16th.
haven't been to federal donut yet, but plan to!
Other thoughts? I really like all of these, but I'm hoping to find new options.
