Do NOT buy food/groceries or do clothes shopping anywhere near yale. They will overcharge you.
Unique Suggestions: ?
Fun Alternatives: TRy and hold out and drive to Hamden Plaza - 15 mins away and go to Stop n Shop or Shaws for food and either Clinton or Tanger Outlets along the Shoreline or the Post Mall in Milford.
While Sally's and Pepe's on Wooster St. may be the famous places for pizza, they simply are not worth the frequent 1 - 2 hour wait (depending when you go and how many people are in your group). Also, be aware that ALL they serve is pizza- if someone at your table wants something else, they will be out of luck.
Personally, I think their pizza is way too oily too. Did you know that the "secret" of New Haven pizza is to pour olive oil directly on top?
Unique Suggestions: If you insist on going, either go really early (like 5 PM) or really late (after 9?).
Fun Alternatives: If you want excellent New Haven thin crust pizza, try Modern Apizza on State St. They may have a wait but it won't be nearly as long as the Wooster Street places and there are other options of things to eat.
