Subway in Diamond Bar

“Very convenient for what i needed at the time. Dental issues req'd tuna (soft eats) & this is located 1/4 mile fr fwy on/off ramps so quick in & out coming & going. Was in town for work, google mapped it & whoop, there it is. Not crowded at all, parking always right in front when i was there & staff was as they usually are for my custom sammiches, ?“
