Use array.filter(item => item.tag.some(checkTag)).map(item => item.name)

	> let array = [
	...   {
	...     "name": "CoffeShop",
	...     "tag":[
	...       "Coffee",
	...       "Cookies",
	...     ],
	...   },
	...    {
	...     "name": "TeaShop",
	...     "tag":[
	...       "Tea",
	...     ],
	...   },
	...    {
	...     "name": "IceCreamShop",
	...     "tag": [
	...       "Ice Cream",
	...     ]
	...   },
	... ]
	undefined
	> 
	> let tags = ['Coffee', 'Cookies'] 
	undefined
	> 
	> 
	> function checkTag(tag) {
	...     return tags.indexOf(tag) > -1
	... }
	undefined
	> 
	> array.filter(item => item.tag.some(checkTag))
	[ { name: 'CoffeShop', tag: [ 'Coffee', 'Cookies' ] } ]
	> 
	> array.filter(item => item.tag.some(checkTag)).map(item => item.name)
	[ 'CoffeShop' ]
