Hi M.,
I live in stevens, which is right next to Ephrata. Make yourself familiar with Route 272! There is Weis MArkets, Redners Warehouse (next to each other). There is a Super Walmart that is a grocery store and has very reasonable prices. There is a place called the Green Dragon which is open only on Fridays. The Amish & mennonite farmers sell their produce and fresh meat. There is a store called MArtins Country Market on Route 322 that is a nice place to shop as well. Talk to your neighbors and see where they go. I personally go wherever I feel like going that day because they are all good. Weaver's market is popular but expensive compared to most of the others.
I have lived in the area for 2 years but I have family that has lived here their entire lives. It's a nice area. I am not sure if there are "bad spots" in Ehprata itself but further north is very safe. Just about everyone around here says hello to you whether they know you or not. I don't know much about Ephrata's school system but I know Cocalico is wonderful. I have an 8 year old. State Street Family Practice are great doctors in your neighborhood.
For the four legged kids, a great vet is Peaceable Kingdom on Route 322, not far from where you will be. They are really nice and friendly.
You can email me privately if you want more info.
Sorry this was so long!!
L.
