I will be in Chicago mid-July and am looking for suggestsions for places to eat. I will be staying at the Marriott in the Medical District about a mile from Union Park. Specifically I'm looking for a place to have a nice romantic dinner, not too expensive (i.e. Alinea is sadly out of my price range). Some nice lunch suggestions too: vietnamese or thai or other Asian cuisines that are on the cheaper side. I will have a car so distance isn't too much of an issue.
Also important: a good pizza place, preferably one that delivers.
