Downtown White Plains has had a rebirth in the last 4-5 years. . .there are several bar/grills along Mamaroneck Ave that seem to have quite a scene if you're single. . . even if you aren't there are some places that have a nice beer selection. . .
There is a big-ass movie multiplex down at the northern end of Mamaroneck Ave as well. . . .as far as stores go, there is very good REI over in Yonkers––google it. . . new shopping center up on top of a big rocky outcropping adjacent to I-87. . they rape you on parking though. . .like a minimum of $3. . .
You could come down to Mamaroneck itself. . . there are a bunch of very good restaurants on the downtown main ave––-Mamaroneck Ave––yeah, it's the same road––-goes all the way up into WP. . .SmashBurger, (just opened, affordable family place, very good burgers AND they have beer!) Molly Spillanes (very fun place––bar/grill), Franky and Fanucci's (thin crust pizza is very good). . . free parking after 6pm. . cool little town, they don't allow any tall buildings downtown, so the main business district kinda looks like a little town out west from the 50's. . .diagonal parking and all. . .
