Starbucks and Luckin are in a fight for the global coffee market. I visited both to see how they stack up on price, menu, and vibe.

Luckin Coffee is challenging Starbucks in Asia and now eyes the US market. Starbucks faces sales declines globally, while Luckin's innovative approach with tech and pricing gives it an edge. Luckin's expansion in the US may face challenges, but Starbucks' pricing opens opportunities for Luckin.
