its easy to hit up all the shops in less than 2 hours
start in union square. go up post street till you see the black hundreds sign. go in if you want. if not, keep going till you hit the end of the street and go up one street to sutter. make a left and go up sutter mabe 2 blocks? you will hit huf on the right side after this coffee shop. walk down to union square and go to the department stores if you want (macys, barneys, etc) keep walking down to market street and take the 71 bus for $1.50 ( i think theres 2 more but i cant remmeber off the top of my head. its easy though, the sign next to the bus stop wil say) to upper haight street. get off when you see the stussy store. from there you can shop at true, true soles, stussy, kid robot, buffalo exchange, and al these other spots. once your done take the 6 bus back to market.
