php - SQL query finding maximum for two joint tables by category -

-

i'm wondering how find maximum of each category if have join 2 tables.

i have 2 tables. restaurant possesses name, address, cuisine, county (area) , rid (restaurant id).

i have inspection has rid, idate (date of inspection) , totalscore (the inspection score restaurant).

say have display cuisine of restaurant, name of restaurant, address , totalscore (from inspection class). have list best restaurant each cuisine in particular county ('cobb' in code) , date of inspection must in 2015. instance, chinese cuisine "beijing central" totalscore of 99 (out of 100).

so far have code: 

    select distinct cuisine, name,address,     max(totalscore) restaurant r join inspection on r.rid = i.rid     county = 'cobb' , year(idate) = 2015 group cuisine, name,      adddress;

while gets me close, keep getting duplicate copies. instance, lists 2 different chinese restaurants instead of choosing best one.

i'm trying improve sql coding style if has solution or best practices, appreciated!

----edit--- here of sample data database when join inspection , restaurant on rid. 

 rid | idate      | totalscore | name              | county | street              | cuisine  | +-----+------------+------------+-------------------+--------+---------------------+----------+ |  13 | 2015-01-04 |         90 | heirloom          | cobb   | 2243 akers mill rd  | american | |  14 | 2015-01-27 |         49 | china moon        | cobb   | 2810 paces ferry rd | chinese  | |  14 | 2015-02-27 |         83 | china moon        | cobb   | 2810 paces ferry rd | chinese  | |  15 | 2015-03-27 |         77 | house of chan     | cobb   | 2469 cobb pkwy      | chinese  | |  16 | 2015-03-18 |         47 | love sushi      | cobb   | 2086 cobb pkwy      | japanese | |  16 | 2015-04-18 |         87 | love sushi      | cobb   | 2086 cobb pkwy      | japanese | |  17 | 2015-05-18 |         90 | douceur de france | cobb   | 277 s marietta pkwy | french   | |  18 | 2015-05-22 |         59 | swapna            | cobb   | 2655 cobb pkwy      | indian   | |  18 | 2015-06-22 |         75 | swapna            | cobb   | 2655 cobb pkwy      | indian   | |  19 | 2015-06-18 |         32 | mezza luna        | cobb   | 1669 spring rd      | italian  | |  19 | 2015-07-18 |         98 | mezza luna        | cobb   | 1669 spring rd      | italian  |

desired result like

indian: swapna : 75 chinese : china moon : 83 italian : mezza luna : 98 ...etc etc

it great if can create sql fiddle. if understand correctly want select max value each group (cuisine). should here how that.

here how query like:

select r.cuisine, r.name, r.address, i.totalscore  restaurant r  join inspection  on r.rid = i.rid county = 'cobb' , year(idate) = 2015 , totalscore = (select max(i1.totalscore)                   from restaurant r1                   join inspection i1                   on r1.rid = i1.rid                   r.cuisine = r1.cuisine);

hope work, couldn't test because didn't provide data in question...

gl!

edit hi edit in question try create 2 table use in query , test it, , query forks fine... here sql fiddle can check scenario , add data can tune query if needed.
