My first trip to the Mason Jar resulted in an okay experience, which is worthy enough for another future visit to see if things improve a bit.
Our server was very friendly, but she forgot to tell us about the specials/appetizers listed on a board by the television set, and we didn't discover this until long after we had placed our order. This really stunk because the fish dinner option sounded very good. Anyway, I settled on a pulled pork sandwich, and the wife chose the Greek burger. The food was served very fresh and the wait wasn't long at all. The pulled pork was decent, but seemed way too salty to me. I've never had salty pulled pork before so this was odd to me. The fries that came with it were okay. My wife absolutely loved her Greek burger and really enjoyed the fries that came with it as well.
We decided on desert, so we got the smores in a mason jar. I would recommend staying away from this because they give you way more than you need, and it just didn't "wow" us. My wife had their peanut butter crunch dessert a few weeks back and thoroughly enjoyed it.
So in all, I'll give them another shot. I wasn't wowed, but the wife loved it.
