As a native, I've probably driven past this place over a million times. It doesn't really pop out on 7th street. My girlfriend and I decided to check it out on a whim of the steering wheel; best impulse decision ever.
When we walked in and were seated, the incredibly friendly waitress placed our napkins on our laps and began reading the specials in a way that would put the Ritz to shame. My girlfriend looked up and our gazes met; this was going to be 4 star expensive. Alas we were wrong, the entire meal was around that you would pay at a low-end chain restaurant. Now the food, the reason for the establishment's existence: unforgettable. I ordered the Zingarela. No words describe but delicious.
Word was spread quickly. I brought my dad to lunch for Father's Day. I've never heard him praise food like he did that day. I'm pretty sure he annoyed the waitress my constantly pulling her aside to tell her of his amazement.
As a whole, don't let the restaurant's atmosphere dismay you. At times it's slow, other times busy. The demographic is older. These things, if they matter to you, will melt away when you take that first bite. It won't be your last.
