i've only been to montreal once, and i live in nyc, so i think you can see where this is goin:
take one of those tourist bus' around town
go to scrap yard/5ptz is where its attt
go see ripleys or the wax museum on 42nd street
get pizza at lombardis, or two boots
lol but seriously i'd recommend lombardis or two boots for heady pizza, and jut go out and walk around. that's really the best . walking across the bridges in the lower east side (manhattan, brooklyn and williamsburg) is nice for sure also. have fun, update this thread!
