where is parking located? i don't see where you can park at

You have to park in the public parking lots or on the street

I park by the Marta. And it plenty of parking on the same street

Yes, several parking lots within 2 blocks. Or take MARTA train! Rays is literally where Peachtree Center station escalator comes out on Peachtree Street.

I parked on the next street behind it and you can go thru a walkway over the street. You come out next door to the restaurant.

Sorry, not sure. I walked from a nearby hotel.

I was at a hotel nearby and walked over, however there are parking lots in the area.
