RENO, Nev. — Eldorado Resorts plans to make more than $50 million in improvements at its three casinos in downtown Reno over the next three years, company officials announced Monday.

The project scheduled to begin before the end of this year includes the renovation of 4,100 guest rooms, new restaurants and casino upgrades at the Eldorado, Silver Legacy and Circus Circus hotel-casinos, Eldorado Resorts Chairman and CEO Gary Carano said.

The move comes on the heels of last week’s announcement that Eldorado Resorts has agreed to buy the Missouri-based Isle of Capri Casinos for $1.7 billion — a deal that will increase Eldorado’s holdings to 13 properties nationwide.

The upgrades at the three Reno casinos include a new 20,000-square foot luxury spa and a New York style pizza place at the Eldorado, and improvements at the race and sports books at the Silver Legacy and Circus Circus.

Canter’s Deli, a favorite in Los Angeles for 85 years, will open a restaurant in the Silver Legacy this fall, and the carnival midway at Circus Circus will be transformed from a traditional American circus motif to a “more whimsical European feel,” the company said in a statement.

Carano, whose company has owned and operated the Eldorado since 1973, said a detailed analysis was started last summer to develop a comprehensive master plan for the three connected properties covering eight blocks in downtown Reno.

The move came after the company acquired the remaining 50 percent of the Silver Legacy and all of the assets of Circus Circus.

“Downtown Reno’s renaissance and re-emergence as a vibrant growing economy has been remarkable and as the leading gaming and lodging operation in the market, Eldorado Resorts will continue to benefit from the increased economic, tourist and local activity,” Carano said.

Expanded air service, improving housing values, higher employment rates and the arrival of new data centers and high-tech firms such as Tesla Motors and Switch have helped spur economic optimism in the region, he said.
