Stopped by 1 Oz Cafe in Mountain View and this place is such a hidden gem! The menu has a creative twist on both drinks and food, and everything I tried left a great impression. •Cinnamon Honey Vanilla Latte: Absolute must-try!

★★★★★ — Shubham, 2025-06

This is the best coffee shop in Mountain View/Los Altos/Palo Alto area. The staff is very kind and friendly and their coffee is sooo good. They have pastries (sell out quickly) and ground beans for sale too. I love their rewards program, if you come there quite often you’ll get a free coffee for every 9 cups you had.

1oz Coffee has a great vibe and clearly cares about quality, but my experience this time fell just short of what you expect from a specialty shop. I ordered a $7 specialty latte, and they forgot the syrup. Instead of remaking the drink, they just added the syrup afterward — which kind of defeats the purpose.
