Tuck is the best thing you can ask for in a neighborhood restaurant.
They value the local clientele with a genuine wink and nod, maybe a handshake or a "how's yer mom?" kind of comfortably friendliness. But, if you're not from the neighborhood it's ok! You'll be treated like part of the family anyways.
The head of the house, John, is one of the easiest people to talk with I've ever met. My second visit was a month away from the first and there was not only a "hey welcome back!" but a few inquiries about a conversation from my first visit. Visits 3-6 were even better. His balance of friendly and professional is top of the charts. I pride myself on being easily social but this guy can talk to *anybody*.
Don't be afraid to sit at the bar, either. It's small and quaint and handled perfectly. I could swim in their gin and tonics. In fact, I think I have, it's kinda fuzzy.
This is one of my favorite places to eat in Phoenix, and I eat out a lot. It's also one of the smallest restaurants in Phoenix so take that into consideration. Friday night at 7 isn't the time to walk in and expect a table for five. However, I would wait longer here for the experience than I would for a Bianco pizza or a plate of Matt's Big Anything (both of which I'm willing to hang quite a while for!).
