What kind of shop is that?
SELECT T1.Shop_Details FROM SHOPS AS T1 JOIN TOURIST_ATTRACTIONS AS T2 ON T1.Shop_ID   =   T2.Tourist_Attraction_ID WHERE T2.How_to_Get_There   =   "walk"
shop type or details refers to Shop_Details; join condition implies correlation between shops and tourist attractions; filtering based on accessibility by walk refers to How_to_Get_There = \"walk\";
