The menu at Blue Bottle Coffee contains no specialty drinks or flavors.

CHICAGO — At the epicenter of restaurant industry innovation and growth are fast-casual concepts with unique positioning and a focus on quality ingredients. An example is Blue Bottle Coffee, a boutique coffee cafe that serves only basic espresso drinks — no pumpkin spice lattes here — and doesn’t offer WiFi for customers.

“They really want customers to experience the natural flavors of coffee and not have anything interfere with that,” said Lauren Hallow, associate editor of concept analysis at Technomic, Inc., Chicago. She and Darren Tristano, executive vice-president of Technomic, discussed emerging restaurant concepts during a presentation for restaurant operators attending Technomic’s Restaurants Trends & Directions Conference on June 24 in Chicago.

“If you’re an operator, look at things brands are doing differently and figure out how to bring higher level and quality to the service,” Mr. Tristano said. “Building a culture and supporting your community not only brings up your brand locally, but also improves the way people look at the restaurant industry in general.”

Common themes among the 12 restaurants highlighted in the presentation were sustainability, local sourcing and community involvement.

“It’s really important for operators to establish a place in the community,” Ms. Hallow said. “Customers really want to see you as a neighborhood restaurant and not just a chain.”
