Kingside Diner

What Kingside Diner does

Kingside Diner is a privately-held restaurant group operating four locations across the St. Louis metropolitan area under the legal entity Diner Experience LLC, founded in 2015 by restaurateur Aaron Teitelbaum. The company is differentiated by a chess-themed brand identity rooted in an affiliation with the internationally renowned Saint Louis Chess Club and World Chess Hall of Fame, which sit adjacent to the original Central West End flagship at 236 N Euclid Ave. The portfolio comprises three dine-in locations (Central West End flagship, Clayton at 8025 Bonhomme Ave, and the Lambert International Airport Terminal 1 concession) plus the Kingside Express carry-out and delivery format at 6170 Delmar Blvd in the Delmar Loop.

The core offering is all-day breakfast, brunch, and lunch served in dining rooms and patios, with menu items including build-your-own breakfast burritos, skillets, caprese grilled cheese, and griddle burgers, complemented by espresso beverages, mimosas, bloody marys, and creative cocktails. The company has extended its daypart via Kingside After Dark — a Thursday-through-Saturday evening food and beverage service from 4pm to 10pm at the CWE flagship — and drives morning-weekday traffic through a Third-Shift Happy Hour promotion. Ancillary revenue streams include private events and catering for up to 100 guests, digital gift cards sold with a $10 voucher promotion on $50 purchases, and after-hours restaurant buyouts.

The underlying technology stack is conventional restaurant tooling rather than proprietary infrastructure: Toast Tab powers point-of-sale, online ordering, and digital gift cards; DoorDash, Uber Eats, and Grubhub extend reach into off-premise delivery; and Tripleseat handles private event inquiries and bookings. The customer base is overwhelmingly individual consumers in St. Louis metro neighborhoods, with a secondary corporate and event-host clientele for catering. The business is founder-owned with no disclosed institutional investors, parent company, or external funding rounds.
