Oak Hills

Oak Hills, Long Island, New York is a fictional town where That '90s Show takes place.

Streets (Avenues)
The series' primary locations, Avenues A - C, all lead off of Eastwood Drive.

The series' four main protagonists live on Avenue A, half the series' supporting characters live on Avenue B. Avenue C remains a mystery.

The town also has a "Main Street" and "Clint Street". See map below for further details.

The Pot Spot
As several of the series characters (Loca, Faith, Andrew, Sarah and Alice for sure) are marijuana users, the pot spot is likely a location where people smoke marijuana (although either recorded use of the substance has been indoors)

O-Zone Skate Park
The O-Zone Skate Park is, predictably, a skate park. Kaity Sanders is in control of it. (Loca theorizes that she gave the owner a "BJ").

Gas Station
The group's drug dealer lives here.

Deli
A deli that has decidedly good egg-saled.

Taco Bell
"Ace Spade", an Avenue C character that has disapeared from the website, works here.

Arcade/Laser Tag/Ice Skating
Apparently, this building houses a skating rink, as well as an arcade and laser tag game.

Some Lake
A lake that faces the backyards of Avenue C, as well as the Pot Spot.
