The Steamhouse Lounge Oysterfest is a yearly outdoor block party at 1051 West Peachtree St NW near the Midtown MARTA station on the red/gold line. The event features two days of live music, oysters and plenty of beer to go around.
Walking time from the station is only 5 minutes. Take the 10th Street exit out of the station and turn left on 10th Street. At the first stoplight turn right on West Peachtree Street. The restaurant is one block up the street. If you exit via the Federal Reserve, turn right on 10th and right on West Peachtree Street.
If you need to park and ride MARTA, a good option is the Lindbergh Center MARTA station, just two stops away. There are several parking garages for free daily parking. Be sure to take your parking ticket with you so you can validate it in the Lindbergh Center station on your way back to your car. Look for the machines with flashing yellow lights.
