The Butcher, The Baker, The Cappuccino Maker is about a 10 minute walk and has pretty good coffee alongside their food items. There is also a Starbucks in the same shopping center, though don’t think that qualifies as “good coffee”
If you are more adventurous, 15 minute walk to the south/east, there is a cluster of coffee shops on Santa Monica Boulevard (Miss Melbourne Coffee, Fan Girl Coffee).
And if you fan out a bit more, even more choices…
