Fairfield’s first Indian-American fusion burger concept opened in 2024 with owner Randeep Singh bringing flavors you cannot find anywhere else in the US.
The menu reimagines classic American burgers, wraps, and salads with tandoori chicken, tikka spices, and grilled paneer, creating something genuinely unique in the fast-casual space.

The bright, clean, colorful space features interior design reminiscent of In-N-Out with its open layout and welcoming atmosphere. What really sets this spot apart are the four signature house-made sauces—tamarind, cilantro mint (green), chipotle aioli, and fire sauce—each bringing distinct flavor profiles that complement the fusion concept.
Lamb Burger: Bold Flavor Done Right
The lamb burger showcases well-seasoned ground lamb patty with American cheese, lettuce, tomato, and choice of sauces on a freshly baked bun. Multiple reviewers specifically praise this burger, calling it “juicy and flavorful” with that distinctive lamb taste coming through beautifully.
The provençal flavor of seasoned lamb gets complemented perfectly by American cheese, creating an unexpected pairing that works brilliantly. Customers note the tender meat and fresh vegetables create a well-rounded flavor profile.
The orange sauce (tamarind) earns special mention as the perfect condiment for both burger and fries, adding sweet-tangy notes that enhance the lamb.
Chicken Tandoori Burger: Indian Spices Meet American Classic
This signature creation features tandoori-spiced chicken breast that’s been marinated and grilled, then topped with fresh vegetables and house-made sauces. Reviewers call it “excellent” and note how the tandoori preparation brings authentic Indian flavors to the burger format.

The owner explains tandoori uses breast meat while tikka uses thigh, giving customers informed choices based on preference. The tandoori marinade—traditionally featuring yogurt, garlic, ginger, and warm spices—creates a flavor profile totally different from standard grilled chicken sandwiches.
Every sauce option enhances the experience, with the cilantro mint sauce providing cooling contrast to the warm spices. This burger represents the restaurant’s mission perfectly: taking two cuisines and creating something new and delicious.
Korean BBQ Wings: Unexpected Fusion Excellence
The Korean BBQ wings earn consistent praise from customers who call them “hands down some of the best” they’ve had. The wings arrive plump and crispy with sweet-savory Korean BBQ sauce coating each piece.
Paired with fries, they create the perfect combo according to multiple reviewers who specifically recommend this pairing. The honey wings also get mentioned as equally impressive, offering a sweeter alternative to the BBQ flavor. Every sauce option earns raves, making it fun to try different combinations. These wings prove RG Kitchen’s fusion concept extends beyond burgers, incorporating Asian flavors alongside the Indian-American focus. 🍗
Atmosphere
The interior design reminds customers of In-N-Out with its bright, clean aesthetic and simple layout. The space feels spacious despite being in a strip mall location on Central Place.
Owner Randeep warmly greets customers, explaining menu items and offering recommendations with genuine enthusiasm. The atmosphere rates 10/10 according to multiple reviewers who appreciate the welcoming vibe. Staff walk customers to their cars and thank them for their business—that level of service feels increasingly rare. The family-owned operation shows through in every interaction, making this more than just a transaction. Plenty of parking and well-lit lot add convenience to the experience.
