Ichijo Ekan Sanso & Hokokuji Temple - Eat on the bench?

We plan to visit Ichijo Ekan Sanso and Hokokuji Temple. Hoping to do one before lunch and one after. However, there is hardly any lunch places around Jomyoji bus stop.

If there are benches within the two venues, is it ok to sit and eat finger foods like sandwiches or onigiri?
