Update:
After reading the talk thread on yelp about the welcome diner I am so happy that they are not closing! Turns out they decided not to and now are going to open a second one in the not too distant future.
I am so sad that I came here on the last day that this little diner will be open. I was introduced to this place by a friend of mine who is a regular patron. It was a nice Saturday afternoon so we ate outside and I think the little diner (with 8 seats) was full. I had a single patty cheeseburger and the favorite and a coke. The favorite is fresh cut fries with peppers, onions and a few other things that made this a delicious side dish. It was all soooo good... I am glad I had the opportunity to try it.
