Update: Dad LOVED Mr Mamas! They gave dads chocolate bars for Father's Day and mine was absolutely thrilled about it. He said that the small gift and happy Father's Day wish was a genuinely kind gesture that shows they're personal and caring towards customers, setting a business like this aside from others that offer Father's Day promos simply to bring in business and holds a much greater value than any discount or deal.
He was just as pleased with the service, food, and homey atmosphere of the restaurant. I was telling him how great it is that the place is so heavily staffed compared to the restaurant I work in, which is much larger and busier. He pointed out that well-staffed restaurants, especially small businesses, are hard to come by and make the overall experience so much better because it doesn't end up compromising any of aspect of service.
