"Park Ave below Grand Central"
This location has pretty much everything except nightlife. It's within walking distance to pretty much everything...Grand Central, Port Authority and Penn. It's close to several great restaurants--check out the charming Barking Dog's on 34th (and ask for outdoor seating by the waterfall outside!), Lemongrass for some yummy pad thai, Hong Kong II. The souvlaki platter at the Euro Diner is delish! There is a large movie theater if you walk further east. Next door is a Borders so you have somewhere to hang out while waiting for the movie to start. On the other side of the theater is a drug store (to buy and smuggle candy into the theater!). The street itself is very clean. In the warm weather, the doormen wash the sidewalks every morning so as to avoid that stinky city smell. There are several grocery stores in the area. Just walk east and you will run into Del Monico's and Gristedes. If you are really into walking, Trader Joe's is in Union Square and will have you eating gourmet foods for practically nothing. Shopping--head onto 34th St. and go west. You will hit almost every major clothing store including Gap, Victoria Secret, Old Navy, Daffys (!), Macys, Aerosoles, Payless, and Lane Bryant.
