Eating around temples

When we visit temples (eg in Nara Park & Kyoto) will we be able to buy food/lunch/snacks close to the temples or will we need to bring our own lunch?

There are many restaurants around Kintetsu Nara Station. Outside Todaiji Temple there are also some food stalls.

In Kyoto, there should be some sort of restaurant near each temple. I suppose it depends on the temple, but the typical tourist spots are all within easy walking distance of some sort of eatery.

There is no need to pack a lunch unless you want to eat on the go in order to do more sightseeing rather than sitting and wasting time waiting for food in restaurants.

There are even restaurants and food stalls inside some of the temple's premises.

Tourists are supposed to eat, be it foreign or domestic.

There are many restaurants/coffee shops/gift shops anywhere around touristy places. You will see most between train/bus stations and attractions. Look for locals come & go, i.e. at Nara station, go south a little and there are covered and open shopping areas bustling with locals.
If you want & on a nice day, you can buy a bento box at a convenient store nearby and have a picnic on the bench/grassy area on a temple property. Make sure to dispose the trash properly.
