Starbucks gets mixed reviews, their coffee isn't always considered top-tier, especially by coffee enthusiasts who prefer third-wave or specialty coffee shops, but what Starbucks has to offer if the consistent, cozy ambiance, and convenient locations makes it a popular place to hang out or get work done.
I personally do not like the coffee in Starbucks, but their couches are indeed comfortable. If I would have to order coffee from Starbucks, I would usually get a cold brew, with 2 Splenda, and a bit of half and half milk.
I am not a sandwich nor food expert, but i think their sandwiches are decent.
