My go-to Tsukiji coffee shop is Turret Coffee. Recently had a client who drinks tea so went instead to Hoshino Coffee. The morning service options includes coffee with a ham and cheese #toast for ¥730 ($5.40).
The kissaten overlooks the main Tsukiji intersection.
Tsukiji 4-7-5
Hoshino Coffee is located next to the Tokyo Sushi Academy.
