Oh, dont forget - KidRobot on Prince St for all the fun tokidoki figurines and blind box assortments of other fun characters!
Then theres also GIANT Robot, which has fun stuff too:
437 East 9th Street
Between 1st Ave. & Ave. A, in the East Village
After you're finished shopping, I suggest hitting up Shabu Tatsu which is on 10th st b/w 1st & 2nd ave (authentic shabu shabu! mmm mmm good! make sure you get the green tea ice cream for dessert!) and then after you're full, head up to St Marks Pl to Sing Sing Karaoke, do some sake bombs, and sing "Living on a Prayer" (or any other of your favorite drunken anthems!)
