After adding cube and earthdistance extensions:

cd /usr/local/share/postgresql/extension
psql -d food_oasis_temp -c 'create extension "cube";'
psql -d food_oasis_temp -c 'create extension "earthdistance";'

Better query (turns out earthdistance returns results in meters):

psql -d food_oasis_temp -c 'select name, address_1, earth_distance(ll_to_earth(latitude::float, longitude::float), ll_to_earth(34.040691::float,-118.235984::float))/1609.34 as miles_from_laci from api_location;'

Select the ones that are within a given box (here 3000m):

select name, address_1, latitude, longitude from api_location where earth_box(ll_to_earth(34.040691::float,-118.235984::float), 3000) @> ll_to_earth(latitude, longitude);

Note that best practice here is to run this initial box query (which is efficient), then run an earth_distance < ... on the results to get a proper radius.
