(I'm late replying to this thread, and Alex is probably the only one who knows who I am anyway
).
I've never been to Luigi's (or any other restaurant in Big D), but I concur with BlueBOB's grandmother (from another thread). Having lived in New York, Philadelphia, Toronto, and now Austin:
Austin: Best Mexican food I've ever tasted, though my Mexican-American buddy from San Antonio insists it can't hold a candle to S.A.
New York: Best Italian food I've ever tasted.
Philadelphia: Best cheese steak hoagie I've ever tasted, and they're right up there with New York with regards to Italian food.
Toronto: Best Greek food I've ever tasted (They also have some very good Italian, Chinese, and Thai restaurants. Come to think about it, Toronto has the best food selection I've ever seen).
