Mamma's Kitchen is 5 minutes away from me and pretty much what the OP describes
Mamma's Kitchen has been our family spot for years. It's close by and they're very consistent. It's been run by the same Greek family since it opened. It's casual, family friendly comfort food. The menu is made up of various cliches like fettuccine alfredo and lasagna, but also a smattering of Greek dishes like mousakka. Nothing very adventurous, but the food is good, everything is made fresh and there's zero chance you'll leave hungry. And the gyros are great.
