It appears that Philly has a bunch of really good Taquerias, esp. around the Italian Market. I'm thinking that it might be interesting to try a dish at one place, then another at another, and so on. Of course, my eyes are always bigger than my stomach and I don't know how much I'd actually be able to eat, but.......in any case. What would be the best taquerias in the Market and what are your favorite dishes there?
