I've been going to Sam's for decades! Can't say enough good things about it. Greasy spoon food, souvlaki is to die for! I would say it's a safe "go-to" option. Solid people. For the longest time it was cash only, but the new owners have installed debit now. Only criticism I have is that you have to pay for the usage of the debit service.
Glad to hear the new owners won't change the menu. If it ain't broke...
