you can get away with not having a grinder. i get beans ground at monmouth/flat white/espresso room (selling square mile coffee) there is a bit of inconsistency between batches but i'm still getting shots way better than that from chains or restaurants, and sometimes better than the reputable coffee shops. will get a grinder eventually but i don't feel it's an essential at the moment.
