A colleague of mine tried to take me to Jake's a couple months back. I talked him into Pinky's North. (Which was a disappointment) Well, we did finally got to Jake's for lunch and it was awesome. When you walk in, the greeting isn't overwhelming and there isn't a sense of urgency by the staff but...it's not bad either.
Once we were seated the server was not exceptionally warm but wasn't unfriendly either. (I know I sound wishy washy)
The burger and fries were very good. Cooked correctly. The server warmed up as the meal progressed.
The place is cozy. When we checked out (you pay at the front), the wait wasn't too long.
