For the Browser version, any area with enough intersecting streets will work.

For the Mobile App version I actually found a good reference at this Mashable article:

1. Times Square, NY

Clue: Don’t drop the ball on the eve of your victory!

2. Arc de Triomphe, Paris

Clue: Triumph is délicieux.

3. Batu Caves, Kuala Lumpur

Clue: Does a Galaxian bonus await at the top of those 272 steps?

4. Plaza de la República, Buenos Aires

Clue: Chomp your way to independence down seven lanes of July.

5. Niagara Falls, Ontario

Clue: PAC-MAN and Ms. PAC-MAN can’t agree on which side is prettier: the

6. Aman Square, Ad Doqi
