Welcome to Food FAQ, a new feature serving up capsule reviews of independent, locally owned restaurants in the Chattanooga area. This week, we head to North Shore and zero in on Keystone Breakfast & Lunch, a Philly-rooted sandwich shop with serious swagger and ambition.
Did you say Philly-rooted? Because that alone raises expectations.
It should. Keystone’s proprietors opened in early 2025, and they aren’t dabblers in regional nostalgia. Dominic Santora cut his culinary teeth in Philadelphia kitchens. Alec Mason grew up there, steeped in a mashup of Mediterranean cooking and old-school deli culture. They built the menu themselves and oversee every sandwich that leaves the counter. So when Mason said, “Come back Tuesday, when we make our Philly cheesesteak,” I made a mental date.
Where is Keystone?
On Frazier Avenue, tucked into Chattanooga’s shortest commercial stretch. As you drive toward Veterans Memorial Bridge, it’s on the right, just before the off-ramp to Barton Avenue. If you blink, you’ll miss the white lettering on the window. Plug in “440 Frazier Avenue” if you’re using GPS. And even then, don’t be surprised if you have to circle back.
Is it dine-in or takeout?
Technically, you could lean against the wall and eat. Practically, it’s carryout. There isn’t a single table inside or outside. Fortunately, Coolidge Park sits in its backyard, offering river views, benches, picnic tables and enough elbow room to unwrap a sandwich.
You mentioned Philly. Does that translate to attitude?
Would you have it any other way? When my wife and I entered Keystone, Santora was barking orders from behind the counter, where the sandwiches are assembled in full view of the room. Several customers stood in line or hovered near the door waiting for their names, and I can’t recall seeing more energy radiating from a kitchen staff anywhere else in Chattanooga.
Mason handled the register, greeting customers and taking orders, while Santora and at least two other staff members moved with graceful urgency to fill them. It was a beautiful thing to watch. And I mean “barking” in the best sense of the word. Both men are friendly and fun to chat with.
So what’s on the menu?
In short: the sandwiches non-Philadelphians fantasize about but rarely get.
Breakfast options include a steak and eggs with chimichurri and pepperjack over arugula, the Jersey Turnpike with fried eggs, pork roll and Cooper Sharp, the Shawarma ‘Rito packed with eggs, tots and tahini pepperjack and more.
Lunch leans into Mediterranean and deli crossovers like braised lamb, chicken shawarma, turkey hoagies. The South Philly layers coppa, soppressata and Genoa provolone, while the Ciabatta Bing! stacks eggplant, halloumi, arugula and sundried tomato pesto.
Sandwiches come on Neidlov’s bread – a beloved local staple – or on hoagie rolls imported from Philadelphia. There are hummus platters and salads, but let’s be honest: you’re here for bread, meat and cheese.
Enough suspense. How does it taste?
Here’s where expectation collides with reality.
The sandwiches are delivered Instagram-ready. My wife ordered the Big Cheese, which comes with Cooper Sharp, bacon and avocado on grilled sourdough. Visually, it was a knockout – crisped edges, bacon curled and glistening. Flavor-wise, it didn’t fully cash the check its appearance. The bacon lacked punch. It needed smoke, salt or something else.
I ordered the turkey hoagie. The turkey was solid, and the cheese, oil and seasoning were excellent. But the ratio was off; there was too much bread and not enough filling. And while importing rolls from Philly sounds romantic, this one tasted like it had traveled too far.
None of it was bad, but with this pedigree, “good” feels underwhelming.
Would I go back?
The menu has enough range to warrant another pass – particularly the cheesesteak, which remains the ultimate measuring stick.
What about prices?
A grilled cheese costs $6.50, while the braised lamb comes in at $16. For specialty sandwiches made from quality ingredients, that’s fair territory.
Hours?
Tuesday through Sunday, 7 a.m.-3 p.m. Free parking is available behind the building off River Street – a meaningful advantage in North Shore.
The verdict?
Keystone carries legitimate credentials. Now the challenge is consistency and execution. If Santora and Mason tighten the ratios and sharpen the flavors, Keystone could become essential.
