Speak at normal speed.
You're giving direction to someone to find a foodtruck in NY city.
When you get out of Grand Central Station on Park Avenue. Go straight on to the East Side. Turn left on 57th Avenue and turn right on Fifth Avenue. Go straight on until Transverse Road number 1 in Central Park. The food truck is on the corner of Fifth Avenue and Transverse Road N°1, in the Park.
Great, thanks !
