you should go back - depending on how long ago you went, you would probably like Driggs more now - it has closed up some of the things it needed regarding actually living there vs visiting. You can live without lots of stuff for a week or two, not so much when you are there for 6 months. and they extended the Tetonia/Ashton trail now all the way from Driggs to Ashton.
There is a lot of national forest in west side of the Tetons - guessing you were in the west edge of Teton National Park. You can also go way up by Ashton and visitthe southwest entrance to Yellowstone - the one that doesn't connect to anything else but takes you to Cave Falls and Bechler Meadow trail. That is one of the best parts of the park for sure since it is barely used due to remoteness.
But yes, the Brommins store is really nice in Driggs. They are a IGA based chain of stores owned by a Mormon family that now has 5-6 stores in small towns like Driggs, Alpine, etc and even one in Idaho Falls. But that is why they are not open on Sundays also so you have to plan.
But Driggs has Teton Thai, Royal Wulff and Victor down the road has The Brakeman. Spoons and Knotty Pine so there are better choices now than ever.
However it has a lot more houses than it did 10 years ago - even some developments like Huntsman Springs. So that is the trade off - you get more people, you get more amenities.
Tetonia is probably more like the Driggs of old and only 15 miles away north in the valley. Trust me, I don't see being on the wrong side of the mountain as a bad thing - that is just what keeps prices down and tourists away. That and driving over Teton pass in the winter scares a lot of people evidently.
